Had my APS TT tuned. Torque seems low to me. What do you think?
Here's my setup:
2003 Stock Block
APS Twin-Turbo (this is the original as I purchased it 6 months after APS first introduced it to U.S. market)
600cc Injector (upgraded from original 440cc)
GTM Stage 1 Fuel Return System
UR Crank Pulley
Plenum Spacer
U.R. High Flow Cats
A.P.S. Dual Exhaust
Koyo Radiator
AEM Fuel/Ignition Controller
I am not a FI expert but it looks like my torque is low. I've attached the dyno sheet. Dyno was done on a Mustang Dyno.
Does the dyno look right considering my setup? Comments appreciated.
Torque is low cause you not hitting full boost to redline, check your wastegate actuators...you should be hitting full boost around 4k with that turbo kit...
I don't know what the scale is on your A/F graph, but it looks pretty sloppy to me. Makes me wonder about the rest of the tune. And like Vince said your boost isn't building up correctly.

Thanks for your comment.
What should I be checking? The wastegates are what came with the APS kit and I don't think anyone has touched them since the kit was installed many years ago.

All they were really able to do is add fuel as all I have for control is an AEM Fuel/Ignition controller. Could this be a problem as well?
Could faulty wastegates be the cause of poor boost buildup?
^^^^well i would absolutely get a different ems..anything is better than that..uprev, utec, or emanage ultimate or whatever u can get a tuner to tune in ur area...**** even ss box...any ems will benefit u alot more than what u are using

I am definitely interested in the uprev but would making this change help improve the torque number?
numbers are numbers..whats important is getting the car tuned correctly, which it may be ok now but a good uprev tune would give it a much better all around tune and im sure it would pick up some power and torque from it
