I need some input from guys that have a VIG 2800.Did you use the Trans GO shift kit or did you get your PCM tuned for it.I had my PCM done by MADZ28 so this might be better,but what are the pro,s/cons of either.I was happy w/the shift quality the first few yrs.,but now it isn,t quite as good and i,m wondering what will the shift quality be like after the convertor(and yes the dead opti might have contributed to some degree)The convertor will be installed late summer/fall.
