Yeah i showed you but i know you were busy trying to be in 34325234 places at once.


best runs were 237hp/300tq

I'm loving the torque but i wonder why my hp are much lower.


My tuner is sending me updates via email (with hp tuners). Hopefully we can get a little more out of it :)

Next mod may be a hi-flow cat...which should give me some decent gains.

Yeah, the torque is great but the hp does seem low. How much boost are you running compared to the LNF tune?

What revs for peak torque and hp?

About the same...well actually my tuner made me adjust something and now my Psi shoots straight up to 25psi and holds it for about 1 - 1.5 seconds before going down to about 20-21 and maintains it throughout.

Stock, i was getting 14-17 psi....and it would take much longer to reach it. With my Westers tune it goes straight up to 25psi in each gear before leveling down


The GMPP Sensor upgrade i believe brings it up to 23psi peaks with 20-22 consistant.

I hope this image is fine. I didnt want to make it too big. If you want it as big as possible, just ask :)

That just shows speed, do you know your axle and tire size? I'm guessing that initial bump is the over boost period, but there seems to be quite a fall off in torque as the revs clime. You really want a dyno with both A/F AND Boost to have a better idea of what's really going on. It seems to me like something is getting choked out and you might have quite a bit of power left on the table :huh:

Should I have recieved another sheet? This is all i was given.

If i get a Hp tuner log, would you like to look over it ?

The sheet is correct. It's just that the X axis is in MPH not RPM.

Here's one of my old sheets w/ A/F and RPM. These setups take a bit longer (i.e., mo money). This dyno day was for HP numbers basically not for tuning.

I think Greg hit the wrong value for the x-axis for your sheet. Let me see if I can get him to email you one with the RPM's at the bottom. That dyno sheet is strange though. Both the hp and tq curves look strange to me... It almost looks as if you're losing boost at a really low RPM level...

My guess is the bump was the momentary overboost, then because of some other engine config, the turbo was loosing effeciency as it climbed in the rpm range (engine not breathing so well). But honestly this is beyond my pay grade. CornFed could probably tell you a lot more from a glance.
