Yes I did, he asked me all about my setup. I talked to him for about 30 minutes. He sure likes your set up. He asked me several questions about my tune and he said everything sounded spot on. He suggested that he might go SD but I'm just not sold on it...IDK

My home track is at +1360 ft. and with the crappy humidity the DA is usually terrible. If it is below the actual elevation we stop what ever we are doing and go to the track. It usually hovers around 3500-5000 ft in the summer.

speed density isn't exaclty what hurt me...it was the fact that i'm speed density AND open loop. i had nothing to control fueling except for the ve table itself. think about it, dodges are speed density and you see those things everywhere. if i woulda had some o2 sensors i woulda been ok

4.30's are on national back order, I'm going to 4.56's thats why I topped this thread off.

I've talked to several tuners and most of them are quick to blame my loose 11" converter for the low hp numbers, and I believe them. My current tuner told me his low 9 sec NA trans am with a huge stall only put down alittle over 435 rwhp on his dyno, if that tells you anything. I bet my truck would have put out alot bigger numbers with my old 9" 3600 SST.

I briefly scanned all this, but I say your cam may be the issue + tune.

what is your gear ratio?

I think I'm gonna try to run it in the next few weeks on a different dyno locally to see if it gives a similar curve.
