1997 VQ30 5MT Dyno
well if you had really looked at it instead of doing that, you might have noticed that this car was actually worse than UNtuned. it is MIStuned to the degree that between 4400 and 6500 it gets 300% of the fuel a UNtuned car would get.
thats what i did when i saw ur dyno graphs

none yet 
i'm waiting for a group dyno deal with my local maxima forum. i'm a student so $100 for 3 pulls is quite expensive. planning to hit the track for test n tune in june when i have my suspension and brakes figured out.
JWT ecu 
you're such a d!ck lol he's learning and trying to figure this out mang. wait for the proper tune before sh!tting on his work lol

Unless you guys run on the same dyno, in similar conditions, you cannot really compare dyno numbers, some dynos read high some read low. You can compare curves, not numbers. Dunno how many times this has to be repeated until it sink in.
Finally got the runfiles https://docs.google.com/open?id=0Bx7...Hk4TndzaHhmbjA
And here's my dyno vs maximus92 auto usim that was mentioned earlier in the thread

Someone in the area is offering $50 for 3 dyno pulls, and so I immediately thought of this. Considering my mods and the fuel filter and knock sensor I just replaced I'm thinking I can get 170hp. That's being optimistic
.......................................... ....
Dynoed again today, here's the best run. I didn't care about fine tuning the hump over 6500, was too busy looking at the rest of the curve for the parts I was testing.

For drf 002 it was 10s for the dip and high 12s above 6500. Timing peaked at 30* at redline.
drf 015 averaged out at mid 13s all throughout and peaked at 39* at redline.
Here's the rest of the dynos from this session from my thread:

Well it seems like my vias may not have been working properly after all. I tried switching around the nvcs setting on the eu and the curve didn't change at all. When I had it apart the cup didn't move by hand.. Sorry guys. Kinda sucks, but not much I can do about it now.

I'll put the intake dynos up relatively soon.

Alright guys here are the maf dynos and my notes. I don't feel like typing my notes out so here's a pic of them. The timing noted for each run was the peak value at fuel cut. (7200 in most cases). After I finished with the 3" maf I tossed the 3.5 back on just to see what it would do. Not a huge difference at all, not worth the money on a 3.0 IMO.
Here are the maf dynos, my 3.5" maf vs the stock maf. Both with legnth tuned 3.5" and 3" pipes respectively. The only thing that may affect the results is the front breather was connected to the 3.5" intake, the front breather vented to atmosphere on the 3"
Initial comparison there are some runs in between where I was messing with timing.
After that I immediately put the 3.5" back on and did 2 back to back runs and called it a day.
I also noticed one of my first few runs maxed out at 39* of timing, so with the stock maf I kicked the timing up from 32* peak to 39* because I thought most of the 3.5" dynos were at 39*. There was an avg peak difference of 5.87hp and 3.05 lb ft.
My highest dyno of the day. I forgot to type a "-" into my fuel map at 5.5k. I didn't spend any time fine tuning the hump over 6500.
