I have 3400 stall FUDDLE 2.1 STR
And a few questions I hope somebody can answer

1. naturallay asprirated, driving at 70mph in drive, not over-drive it bounces of rev limiter. when I floor it.
2. at the track with 125 shot. it wont shift in to 3rd just bounces off rev limiter. I even let off the peddle when it hits rev-limiter, still wont shift.
at the track, no NOS I get 12.33 1/4 mile and never hits rev limiter
3. going at 70 mph in over-drive I floor it with 125 shot, and bounces off the rev-limiter, like right now.
I had converter installed by a sponsor, had torque management set, and dyno tune. prior to getting NOS.
Does it sound like converter problem?
I have a window switch, but not installed yet.
I have a toggle switch for NOS, and shutting it off prior to shift, sometimes takes care of problem.

 

install the window switch and see what happens.. i imagine that would be the problem but i could be wrong. If shutting off the nitrous takes care of the problem sometimes then i would say its almost definately the window switch.
