New Dyno Tune Numbers





wow man, thats sick. i wish my car was that fast. how long did it take you to get all those mods into your car?
 
Just had my GTP dynoed today, not what I expected. 215whp/235torque. I thought I would be much higher at least 240hp to the wheels. Something is not right the car has gotten much slower this past six months. Its like driving with the supercharger belt off even though it is obviously not, the dyno setup measured 10.4 psi of boost. Has anyone ever encountered this with no codes and no KR with a "tuned by scan tune" on the car. BTW:My mods:WizAired CAI,3.5"Pulley,NGK-TR6,1.8 RR,3"DP,3"Cat&3"Exhaust.Custom PCM Tune.

Sounds like a crappy dyno or a bad tune...that thing should be making more torque than that

Yeah, I'm leaning on it being something with the tune. I used to run a dhp 1.0 and it used to pick up quick but too much kr under accel & wot which meant too much timing and too lean. Thats why I went with a "tune by scan" starting with a stock bin via email. It now has no kr but as you can see it can be much better. I dynoed it a local speed shop 3 pulls @$60 weekend special event. They quoted me $320 for a 3 hour dyno tune. I'll have to put some $$ aside for that one, but the guy there said it should be no problem getting it to where it should be at with the mods I have.

that's what I would have expected with your mods.......except for the torque.....maybe they started the run above 4K?

What is the stock 2001 gtp put to the wheels? That would shed a light on things considerings my mods. At least I made about 50hp or more with what I have, dont you get a 15-20 hp increase with just a cold air intake, plus I have roller rockers and the exhaust mods, so something is holding the power back.

One thing though besides the tune that comes to mind is that I swapped out all my injectors with flow-matched zzp reman'd injectors when I got my LIM gaskets done and the car became alot quicker which slowly declined since last winter. So I don't know if the they are at fault but am just weighing out the variables. There are no codes or KR as I mentioned in my first post so I would think something would set if fuel was lacking to the engine which seems is not the case. So as some of us said it has to be the tune.
 
stock they put down between 190-195. You don't have headers or a PEMs, 1.8 rockers don't do crap (at least not on my car). Do you have a colder stat?

You really need some headers
 


I sure would like to get some help I own a shop here in Jacksonville Florida, we had a customer bring us a 3.8 02 GTP, I do mostly Ford and use SCT, so please do not throw rocks at me, well this man had us install new heads, Nitrous and a inner cooler, now the inner cooler is not real impressive, in the first place it does not even have a reservoir, so I added one I will post pictures tomorrow, today the IAT was up there it was 95 degrees here, along with this I added Apple green 42 pound injectors, the car has a larger TB and a Cardone Maf, he bought a ECM from ZZ Perf, and we added larger exhaust, and the ECM is supposed to calibrated for the Maf, I had the TB powder coated and the S/C as well and had the VC painted all gloss black the install is perfect it really looks good, I sucked the stock file out from ZZ and made the change for 42,s but I can not get the AF straight it is a steady climb lean at WOT, so I am fairly frustrated, I will check FP tomorrow and I will solve this. I want to expand my platform to GM, and I know this takes time, but I sure need some guidance here and any help would be appreciated I thought some of you would like this, it is my daily driver it made 660 RWHP on a 75 shot with a Novi 2200.


Here is the dyno run with the 75 shot you will love the purge shot.

I was right the pump was the problem, the AF is now 11.6 so can some one tell me what a car should make on the dyno, with pump gas

Here is the first pull on the dyno with the new pump. I know the car has more, what is the average with this setup.
