Well i finally dynoed my truck today. heres the numbers
203.00RWHP
264.60RWTQ
@13.7 A/F ratio
first run was the best, second run the truck pulled timing and i lost 4hp. Unfortunately, i still have my stock tune with the speed limiter set at 98mph. so my numbers aren't as high as they should have been. but good enough for baseline.

Now you have your baseline, so get busy modding!
Gone, but not forgotten!
i already have all the bolt on stuff in my signature, i dont feel like investing too much into the 4.8L while i'm building a 5.7L to replace it

tuning will come soon enough, runs great for now. i figure allen can squeeze another 20hp out of it the false knocking is a problem though, noisey lifters.

Well, if you are building a 5.7, then quit wasting $$ on the 4.8

DUh! thats my point chuckle heads, i've done all of the easy bolt on stuff. i can get performance now with the 4.8L and when i put the 5.7L in, i wont have to do any bolt-on mods, they'll already be there. now thats a plan!
