SuperSilverado53

The truck finished up this today. It made 610hp, and 628tq at 16psi,13 degrees of timing and about a 11.0 AFR. It was tuned by John and dyno'd at Dyno Lab shop. I still not satisfy. I am not going to give up until it is successful. Seem not right, I need your help. I just try figure out what reason cause problem is. My friend who did tuned and He said It's just barely peaking at 16 should be around 700 but loosing a few #'s because big trans and converter. If the boost came up quicker, the motor would spin harder and faster and probably make a little more. and drivetrain loss is quite a bit more than normal with the 80 trans and big converter. He said remember my cams pretty conservative. That will limit what the motor can flow too. And that's probably why it doesnt make power beyond 6000. Also, He said if the wastegate is in the best position(near the turbo, venting Both sides of the motor) then technically, the boost will be controlled correctly. My setup is 6.0 LQ9 full forged built 9.5 cr and my turbo kit is KB racing wg 50mm, and Borg Warner 75mm turbo, 4" DP, Eboost 2 controller elect., 317 head cylinders, Pat G custom ground cam 222/222, .601/.601 115lsa, Cam comp dual springs .675, 4L80E w/hd2 and circle D 3,200-3,400 stall. Im gonna upload the pic of the dyno graph and video.

Still good numbers. Very close to my setup, actually. Are you locking the converter on the dyno?

Oh Thanks, Cool! correct, he said yes, did lock the converter.

Dont worry about the numbers. Dynos always vary depending on the type and some read lower than others. Some have a harder time loading a turbo. See what it runs at the track.

Not sure I am guessing you want 700?
Your gate location is fine. Been doing that for years.

I would think it would be higher aswell. Do you have the 1.10 or 1.32 AR on your turbo? I have the same mods as you except a little bigger cam and I can guarantee I'm over 600 on 13psi.
