hello everybody, i have a 2006 gp normally asperated 3800 series 3 engine with dual exhaust. does anyone know of a programable tuner for the ecu that will allow adjustments on fuel and ignition curves. as well as adjustments to transmission shift points and line pressures, as well as upper road speed limiters? what are the most cost effective ways of increasing hp for this engine and trans combo? I would appeciate any help that you can offer.

Hi people..Im a new guy to this site...i ask the owners of a 04' grand prix questions about their shift points or like a snatching in there 1st and 2nd gear shifts...also I've noticed when i cut my car off for like 15 secs, then cut it back on, the shift snatching goes away...and another thing is it shifts right every blue moon, but when it doesn't, it kind of lags on the shift in the 1st and 2nd gears...its not a swift precise shift..any pointers from those who have had this problem? or does anyone kno what the problem could be?
