As you all know my tune on my car is GARBAGE AFR is all over the place. I have Haltech with a Haltech Dual wideband controller. the shop I went to did not calibrate the widebands before they put them in. So now Im getting 220 miles per tank...GARBAGE AFR. I am getting like 11.0 on one bank and 13-14 on the other bank. Car starts bogging goes extremely lean to like 18-19 AFR when accelerating at times and stalls. Worked with Surratt and he helped me tune the car a bit and get it running a little better. I been down to the shop 3 times to correct this and each time just seems to get worse!!! So I was talking with Surratt and he said that I need to remove the widebands from my headers and calibrate them in the free AIR like the instructions I TAPED right on the freakin BOX and gave to the shop...I guess they shose to ignore them!!!!

So the other day I jacked the car up and was going to take the widebands out to calibrate them. Keep in mind I told them to REMOVE my primary O2 sensors from the headers and place the widebands in their position so I can get accurate readings on each bank and weld bungs in the y-pipe and place primaries there just so I dont throw codes. This is what I found when I got under the car.

REAR CATTMAN HEADERS with STOCK O2 SENSOR PRIMARIES STILL IN:



FRONT HEADERS with STOCK O2 SENSORS STILL IN!!!!!:



WIDEBANDS WELDED INTO REAR OF Y-PIPE!!!!!! SEE STOCK SENSOR IN REAR HEADER ABOVE!!!!!



HALTECH WIDEBAND WELDED FAR FROM FRONT HEADERS IN y-PIPE!!! STOCK O2 SENSORS STILL IN FRONT HEADER 2 miles AWAY!!!!



I guess they were TOO DAM LAZY to remove the stock O2 sensors from the headers and put widebands there!! No wonder my AFR is way off and TUNE way off. On top of not calibrating widebands LAZY BUMBS put them in the y-pipe and I SPECIFICALLY TOLD them EXACTLY WHAT I WANTED!!!!!!!!!!

This is my warning to everyone out here: All these shops out here claim they the best and they know this and that!!! BE CAREFUL!!! Check the work they do with a fine tooth comb!!!! Dont trust NONE OF THEM!!! MOST OF THESE shops just want your money!!! Freaking BUMBS!!!!! I was so disturbed by what I saw I just put the car down and decided to forget it. Im not even driving the car anymore. Taking it next week to get the turbo installed and this local shop does things right and they will swap the widebands with stock primaries!!!!

 

That's ridiculous! Why would they just do that without at the very least running it by you first? I mean, if they thought that you were wrong and that the widebands needed to be installed downstream, then the best thing they could do is phone you up and say "Hey, I think you should do it... [such and such way]" and then you could tell them "No."

That really sucks man. Not sure how long that's been that way, but the extra money it cost just in gas (getting only 220 miles per tank) would have me beyond livid.

I don't think they thought it was better. I think they are INCOMPETENT that is what I know. Widebands should be in the headers.

 

First suggestion Make them buy new exhaust because of wrong bung placement then get them welded correctly.

 

one of those things, somethings don't get done right unless you do them yourself. sad to see a performance shop do such a horrible job. IIRC they were a nissan perfomance shop right?

some people dont read directions no matter how much trust you have with them, its a shame but its hard to say how to correct that part of the process.

 

I didn't get past the welds, never mind the placement. Even in high school, if I had produced a weld like that the shop teacher would have held it up for every class as an example of how not to weld something.

 

No, they don't claim to be a Nissan performance shop. They do alot of Evos, and Sti and 240sx seem to specialize in Turboing cars. That was the reason I went with them. A really **** POOR job!!!

 

That sux dude, big time! That's why when my car goes to a shop, I hover over the wrench working on it - as much as they may hate it. Many times, I tell them to do things a certain way, and they will sit there and try to convince me I'm wrong, or it's unncecessary. That's the honest ones.

One time at Evan Tires I went and bought a new set of tires & lifetime alignment for my wife's 4Runner. They tried to sell me a brake job & shocks/struts (brakes had been done a week before & struts were still under warranty). Since I refused, they put some goop on my front brake pads and a day later, they were ruined.

I trust my regular mechanic, but not enough to let him work on my car unattended - let alone other mechs I don't know well, especially after the above incident at Evans.

 

Damn man that sucks putting extra bungs you didnt even need, and your csr not running right, but Good Luck on the Turbo....

 

SMH, I would of went crazy.like everyone say you have to guide and keep eye on when people working on your car sometimes they think because there mechanic and technician they know more than other people do which is not true.Good luck with the next setup.

 

damn thats just crazy

 

damn maximas going against the grain and being modified, such a pain in the butt car to modify performance wise

 

but the rewards FAR FAR outweigh the negatives!

 

did you explain to them exactly where you wanted the o2 sensors to be? Just b/c they are a "high performance" shop that means nothing... its not what type of cars they work on or the name or the equipment... its the actual mechanic who does the job... if he is someone who knows how to weld but has no idea about wide band 02 sensors and so on its not his fault...

 

I still don't understand why you don't have them make it right or ask for a refund.

I would never drop that much $ and let someone get away with **** show of an install.

If they did that bad of a job on something as simple as o2 sensors everything they touched is suspect. You need to go back and double check everything and then bring the car back, point it all out, and get a refund or have the work done correctly.

If they refuse to fix or give you a refund contact the BBB and make it public what they did by writing in the local paper etc. No reason to let some hack performance shop bend you over and give it to you raw like that.

 

It was explained in detail..........explicit detail. It is ultimately THEIR fault if they did not tell the welder or WHOEVER did that what the customer wanted. I talked with the person that installed the stuff. They were supposed to install one step colder spark plugs too and he told me that he had already put the manifold on and that the TUNER (who I spoke to in charge of the shop) did not tell him that he needed to install plugs......so if they are not communicating then that is THEIR fault. Am I supposed to go to all 6-8 guys in the shop and tell each one what I want???

well....I have been back over the tune 3 times. 1st time street tune to stop the bucking and car running lean. the second time was because it was still giving me terrible gas mileage. 3rd time I returned for them to make more correctiong on the gas mileage because it was still garbage. Thats when I found out widebands were not calibrated and told them, but they swear they calibrated them. I also talked about them disabling the O2 sensor control and what tuner told me was "People who dont know how to tune use that. If you tune the car right you dont need that." Its just the whole attitude of the shop I don't care for. They want me to bring the car back in so they can correct but I dont feel I should have to drive another HOUR down for them to screw my car up even more. I'm done.....going turbo now anyway. I don't have time for this fighting with a shop. I dont trust them to do anything to my car anymore. That is why I got my equipment and just got the hell out of there. you reach a point where travelling back and forth taking days off work and crap is just not worth it anymore. If I was broke and I spent my last dollar on a tune and all that I would be up there in a heartbeat...but thats not the case and this is a battle that will only be to my disadvantage rather than advantage. Because I dont want them to do something to my car and make it worse because they get pissed and decide to be slick. So I'm cool. Its not like when I had to go through that crap with SFR and them not sending a $2000 HALTECH that I ordered 4 months ago. THAT I WILL FIGHT FOR!!! AND I won that chargeback dispute too! This is not worth my time and money that will ahve to be spent over and beyond what I already paid.

 

understood.

You experience with SFR has always left me worried using their products.

 

I would post this on as many review web sites as I could find. Hell, I'd even go as far as making flyers to post around town. Of course get your money back and all your complaints resolved to your satisfaction first!
