slight stutter under light load
The build is complete, roughly 4xx miles on it now. since I have started driving it after the rebuild I notice a very slight stutter, almost misfire like I've never driven a cammed car so is it possible that its normal? .ALSO just got the computer back from madz28 I'm now noticing a bad egg smell ever since I got the computer tuned, it was fine before hand not exactly sure what may have happened there.

Is this a stick or auto car? When do you feel the studder and what RPM?
Are you sure the egg smell isn't from the bad Mexican you ate the night before?

1200-1500 you shouldn't be using the gas pedle and lugging the engine lol. However it can probably be ironed out in the tune. Mail order tunes are never exact unless you data log and send it back and fourth. My suggestion at the very least is log you car get/ watch a wideband and dyno it to see what's going on.

At 12-1500 rpm other then when in forst taking off from a stop light you are probably loading up the motor. Even woth a lt4 cam that low of rpm is bad for it unless on highway or just starting off in 1st and even then should be minimul throtle. The converter may or may not be bad. May be whatever the tune is set to is making the cat smell. Or it could have made it go bad no way of knowing wothout knowing whatthe car is doing.

sounds like misfire
bad egg smell is usually a cat. I would data log it and see whats going on, my old car used to misfire and not throw an ses, but hooking up to HPT a few cylinders were having tons of misfires.
