I sent Allen my pcm and got it back last thursday, the truck is running fine, I do have a couple more pics and I will try to post them in the next few days. As I told Allen we have some big hills here in Arkansas and I use one to check my performance on by leaveing it in 5th gear and see if I gain or lose by the time I get to the top. My 4.8 with headers, slp pulley and hppIII would break even to maybe gain 5 mph, I have tried once with the LS1 after I got my pcm back from Allen and I gained 24 mph on the same hill which I was proud of.
