TurboTrix tune...why is the torque so low?
Had my car tuned at TT two-three weeks back, put down 333whp/308wtq with the following mods. It was 86 degrees out with 10-11% humidity.
GSC 272/272
Helix 3" TBE with straight pipe
Helix Intake (hardpipe w/ cone filter)
Hallman MBC
Walbro 255lph fuel pump
ARP Headstuds
TurboTrix reflash
This is on an 05 Evo, so I also have the 10.5 hotside going for me. I added a Forge BOV after the dyno tune to replace the stocker.
I was expecting anywhere from 340-350 for both HP and torque and needless to say wasn't quite pleased with the results. I suppose my whp is only 7 horses away from the minimum I'd expected but the torque is a good 30+ away.
I did do a compression check before the tuning and it tested 190,185,190,190. I tried to do a boost leak test but the tester itself sprung a leak at 12psi...I didn't hear any other leaks in the piping at that pressure, FWIW.
Is it just the tune or is it my mods causing the numbers to be subpar?

i had almost the exact same results at turbotrix with pretty similar mods. check out Final Tune Results! , maybe this will have an answer for you.

I saw a guy with 360 hp and 317 tq. He had a Busher o2 housing with a built in waitegate.
It sounded like that was leaking under full throttle. Check your blow off valve.....
My car made 364hp 359tq.at 21psi. we will be doing a 26psi pull and hope to see 390hp
on 100 oct. I allways run 100oct. TT trix tune
Stock turbo no Alky

I see many dynoflash sheets that show torque in the 335-350 range with my mods. TT sheets seem to have a lower spike but still have atleast 25-30 more wtq with these mods.
Regardless, my numbers are less than stellar...average at best, which is a bit disappointing IMO.
The car pulls nice up top but it's definitely dead on torque...compared to what my friend's car was like with the same mods. He put down 336whp and 334wtq at the Pruven Dyno.

Ive noticed that TT tunes usually have more HP than a dynoflash but the dynoflash always has the TQ pretty close to the HP #s, if not more TQ than HP. Either way your numbers do seem alittle low. Hows the car feel? Try doing a boost leak test again.
