Here are the autotap logs that corresponde with the dyno results above....

It looks to me like the PCM wont advance the timing beyond 15 at WOT.

You're right. 15 degrees is all the stock PCM is going to give you at WOT, no matter what you do. Every once in a while you may see 16 or maybe even 17 degrees, but it is VERY RARE. 15 is usually all you will see. If you don't get KR on pump gas, you should see 15 degrees of timing as well. Race gas only helps give you more timing if you are getting KR on pump gas. If you don't get KR on pump gas, the race gas is actually going to hurt you because it burns slower. This is why we added adjustable timing to the GTP when we got the PCM programmed, because the 15 degrees of timing it was getting with the DHP PCM was rediculous. Everyone else running that fast has 22+ degrees. My suggestion is get a DHP with adjustable timing programmed into it, and you should see some pretty good results.

You did notice that your making 399.5lb.ft of torque though, right??? Can't complain about that, although I'm sure your tranny will.

You dont 'want HP you want torque
That'* massive torque there dood. More then our Friggun 350 Yukon... :?
That PCM is saying NO to all the power. It'* definetly holding you back. I'm curious to see how much you can free up when you get a solution for it.

Still damn good though.
Funny that even after my header upgrade I haven't noticed any difference in boost at 10.psi with the 3.4" pulley. I would have expected it to drop a couple of psi. :?
Gauging my hp increases since stock 240 bhp, I am estimating 300 bhp. At the wheels, I would expect it to be around 240 whp, so 247 is very good.
How'* the calibration on the dyno since the last time you were there, or is it a different shop?
At least you got a boost in torque and that'* what a street driven car needs.
