My truck Dynoed 310 RWHP and 298 TQ with a cam, stock manifolds and cats with the exhaust unbolted at the end of the Y-Pipe, tune and a CAI. Does that sound ok or could it have done better. Don't forgt it was Florida 96 degree heat that day as well.

 

I would think that you could have made more, but the stock manifolds are killing you. Why does it say you have LT's in your sig? Dyno before you put the LT's on?

I dyno'd those same numbers (before SAE correction) with just boltons.
