Nice numbers. If you had the 5 piece NWP spacer kit it would have made a little more, but remember that you have an automatic with 156k miles. Also, you don't have the 3.5" intake tubing and LRMAF or a tune either. You can pick up quite a bit more from that as well. Those are solid numbers, dont be hard on your car.

) and dynoed 238whp with only a home made Sri, Obx un equal length headers, and a custom crush bend with ebay tip on it lol... This here is essay lower than Avg....

I'm going to have to politely disagree with most of this bro.... Numbers are significantly lower than it should be for a tuned Maxima... Also spacer would beef up his mid range a Lil but it won't boost much of his peak power.... My 5.5 4at untuned that had afr's up in the 18's () and dynoed 238whp with only a home made Sri, Obx un equal length headers, and a custom crush bend with ebay tip on it lol... This here is essay lower than Avg....

OK.....This is tuned??? No where in the mod list does it say anything about what tuning was done. I thought this was just a regular dyno after Cattman headers and all. What you use to tune with?? If this is tuned then YES its low. Also if its tuned then get 3.5" intake pipe and a LR MAF...make the most out of the tune. Again, no where in the mod list does it say anything about it being tuned......

Those afr's aren't perfect but that's waaaaay more tuned than most maximas lol... It's still low however you slice the cake.... Even if it was with absolutely no tune its still low lol... Those are not "solid" numbers but hey, if the op is contempt n is satisfied then o.k

Here is something to compare your AFR's to lol, now you tell me if your car isnt "tuned", maybe not fully tuned but tuned lol.... with SAE smoothing set to 5 the whp was 232... again this is with far less inferior power mods than the OP and when i meant no tune, i meant i didnt even own a tuning device to even attempt to adjust anything.... not trying to bash, but those numbers are significantly lower than AVERAGE...

i dont think new or old was the problem or even burning oil as mines was burning oil from both valve covers when i dynoed, my motor was maybe 140K'ish when i dynoed... if you dont have any codes for anything then i honestly dont know, i guess thats just how your car reacted to the mods

OK.....misfire codes. Now we are getting somwhere. Might have an issue there. The reason I say 234whp for an AT is solid is because DOUG has a FULL TUNE, UTEC, Modified IM with BOP and 2k9 TB, (I think 3.5" intake tubing and LRMAF) and dynoed at 267whp with headers, 3" catback, 5 piece spacers, etc and he AT as well a built AT at that. Now you telling me an untuned AT with headers, 3" exhaust, 3 piece spacer, stock mani, stock TB, smaller intake piping is supposed to make more power than 234whp? I dont know.....Im not the AT expert, but I still think the numbers are solid numbers for an UNTUNED stock AT. What do you expect?? 250whp?? Tuned ATs usually make anywhere from around 250-260ish.

i believe thats where they had the motor similar to the 7th gens

OK, I trust you Hustle. I'm not an auto person. I was just looking at some other 4AT 5.5 Gen dynos with similar mods. I only saw one 5.5 AT that dynoed 245whp with no tune.....I think that was Aj Cool girl. Had FULL BOLT ONS. That misfire might be blowin it though.

the 2K9 TB did nothing for power with dougs car, so thats not a factor really, plus SSIM and BOP may only give you 7whp peak in WHP lol.... Squirrels 4AT 5.5 dynoed 234whp at maxus 09 with only cattman headers and 2.5" catman catback (outside in over 90* weather), 1sexyleo dynoed 243whp with home made intake cattman headers, ebay evoII knock off catback, test pipe and a pulley i believe (none of these cars tuned).. IMO for the small tuning that the OP did i would expect anywhere from 245-250'ish whp... those numbers are "solid" for a 4AT but definately not "solid" for a 4AT with his mods... rod, address that misfire 1st bro, and go back at the dyno, i wouldnt even be surprise that when you fix that you seriously throw off the AFR's and will need to tune from scratch again

Thats for an rpm signal i believe...
And yea, with the tailpipe sniffer, it normally reads leaner than actual. Possibly up to a full point. Regardless, the afrs are still not that bad imo.

Damn Rod, finally hit the dyno eh?
Was this in 3rd gear?
And yeah check out my dyno thread where I discuss the lean/cat reading, make a big difference.
How many runs did you get?
That chopiness looks a little suspect, could be the misfire.
