Just got back from the dyno
holy crap i didn't know that at max you'll get 40wtq from those 3 mods..... wait........ummm i think you are confused....

They quit making power pretty much at 5800 rpms...I believe its due though to the shorter gearing. The tq probably ends quick on these engines because of the small turbos as well.....I believe these numbers are good enough for high 12's if I can get the power to the ground we will see though...I will post up my slips.
The last run they cut off early so therefore it was unaccurate readings....the first run they did fully but it did not record because the guy forgot to hit the record button. So therefore the first run on that sheet is technically my second.
Are your numbers on that sheet STD correct or uncorrected?
OK. Excellent torque number. Highest corrected I have seen for the trifecta tune by quite a bit. The hp will jump up probably another 10 whp if you add a DP. The Dejon intake must help quite a bit. I noticed a difference when I put mine on. I am going back to get redynoed on thurs to see what I make with my boltons and some more tuning.
I think it's actually sized fairly well to the application and still has a little headroom for those who like to modify the car. But there's a reason why it's not going to make a ton more power over the lower 300 mark at the wheels and why those who try will see a massive torque spike in the midrange and diminishing returns on the top end as rpms and airflow requirements through the engine increase. You might call it obsessive, but dang right I'd be looking at air flow (or more appropriately air mass) the stock turbo can provide if you're wondering what it can support and what's to be expected out of a stock turbo LNF.
It's all a matter of perspective. Compared to a Holset on a turbo diesel truck, the K04 is a baby turbo. Compared to the stock T25 on my Grand Prix it's massive.

Humm...TGP! Such great cars in its day! 205hp out of a 3.1 in 89-90.....Those where fun cars, and extremely rare indeed! Have any pictures?
There should be one in my gallery here. I have all the pieces to swap in the Getrag 282 5-speed which should make it a fun driver if I can ever get around to working on it.
Hey guys, I'm looking at the numbers in this post (and I realize they are the highest TQ numbers thus far), but I'm wondering where the gains are coming from in his mods...
1. Is this a 91 or 93 octane tune?
2. Does the muffler delete do anything power-wise for our system?
3. I may go K&N to remain stealthier at the dealer - I know they can find out about the tune, but do they actually check all the time? Probably not. But then, what do I know? I'm sure I'll lose a few HP though.
4. What does one expect the 91 to 93 octane difference would be in our cars when tuned? I can get 93, but rarely. It would make road trips a huge pain.
Thanks,
Mal.

the power is coming from the ECM really. the stock ECM limits power to 260hp. The tune eliminates that, and allows the engine to make the 300+whp that it is capable of from the factory
Yes, but his torque numbers is approx 30 ft-lbs higher than the car trifecta developed the tune on and the test car had more mods. Intake may be accounting for some of that extra torque as the test car was using the stock intake, but not 30 ft-lbs.
I've had 3 GP's and really liked that body style vs the change they did in 97 lol. 90 TGP, 93 GTP (3.4 DOHC 5spd) then purchased a 96 GTP (swapped the 3.4 DOHC to a 3800 S/C).....
You simply cannot compare dyno vs dyno...Too many things get involved. The one reason Dynojets are so popular though is because no user input into them unlike Mustang/Superflow, w/o knowing which dyno's both the test car and his car where dyno'd on, its just a waste of time to compare them. Thats why running a stock dyno run is important to see where the mods take you from your stock, and keep w/ the same dyno for your comparsion results with trying to keep relative same conditions as well.

Muffler delete will do nothing but add sound. The most restrictive part of the stock exhaust is the stock cats on the DP followed by the stock resonator. The stock muffler was tested by CIA to flow 560 CFM. The stock turbo flows only 36 lbs per min max which is approx 450 CFM.
how is that dejon intake treating you i put one on my car and it wont run right i took it off runs perfect i got the trifecta tune with dejon ic piping and greedy type rs bov had the cai but like i said with the cai my car ran like absolute **** took it off runs perfect
i dont think he's asking what causes the difference between the test cars power and the posted numbers...i think he's asking why just a tune makes so much power on these cars, which is what i answered
