So. This has caused quite a stir.

Pretty awesome however its fairly clear it was reading somewhat high. I figure a heads and can 5.3 will put down 385ish on its best day threw an automatic. I bet you are closer to +400 seeing as your a 5 speed. I think a guy over on pt.net was saying he saw a difference of 700 HP on a mustanf dyno and 800 on a dynojet. Right day right time and maybe a little wheel spin? Let's all take dynos for what they are really worth.... a tuning guide and measuring stick as we make adjustments. Once again congrats devin. Your build is pretty awesome. The what 4500 mile round trip yo star is proof of what a beast this thing really is.
