I have installed nx setup but I'm disappointed with gain.I am told that nos requires a little timing retard so I removed power tuning and left shift point and rev limiter up.Best with nos 14.99 @ 90 but nos off ran 15.85 @ 85.I have run 15.3 @ 88 appeared stock and outrun any truck I can outrun now without the (yea but you got nos)b.s. I sure don't think I picked up 125 hp. I did this to go after an annoyimg harley ford running low 14's,I ain't even close. Any advise welcome. Jim

 

I would get a 3" cutout before that Flowmaster muffler
I think that your loosing some power with that muffler
Was the run done on a Full bottle ?
Is this a Dry or wet setup ?
what are your 60ft times are you running on slicks at the track ?

Yeah what pills are you running? Mine will jerk my truck sideways and smoke the hell out of my one wheel peel at 55 with mine. Well i run a slighlty larger shot most of the time though. Even with a 100 shot it will break loose though.

 

Full bottle,but it sure does'nt last long,and I did pick up a traction problem.I'm running a 55 pill,29 on fuel side,but I thought about drilling one out to 60+.I guess I souldn't have watched Fast & Furious I expected whiplash.What are your programmer settings? Jim
