You mentioned 400 *ish* from a dyno run with a baseline pump gas tune...

What are the actual dyno numbers (HP, TQ, RPM) from the 10 dyno runs? What was the state of tune for each pull?

I am hoping you eventually got it maximum tuned at some point. What were the results?

Re: Fully built 4.3- $4500 bare $6000 complete

well it was on 2 different dyno's, first time on a dyno jet melted the tranny out of it at 8 psi made 306 to wheels before tranny issue was discovered

on a mustang dyno, at 17 pouinds made 401 HP to wheels, i dont recall RPM

now to put into prospective of power we took a 12:1 compression 383 corvette that has run 11.19 121 in the quarter. weighing 3400 pounds made 306 HP to wheels on this particular dyno

we brought another customers typhoon to this particular dyno and it made 350 to the wheels and has run 11.60 119 weighing 3900+ pounds

the dyno session was cut short with my truck cause of a starter issue, and the truck has never been back since

the tuner was confident that 425 to wheels with the GT-42 was not an issue on a pump gas tune at 17 pounds considering how the plugs looked, and the intercooler was also found to be too small as intake temps were getting warm at lower boost

another random question, did you melt the stock 700, or a TH400?
