Granatelli Predator Tuner I just got one and was wondering if the stock tune on those things will work well with LT headers (QTP) catted y (QTP) and a free flow exhaust (GMMG)
or should I DL a better one?

The 'performance tune' will run better than the stock tune, but it is designed for a stock car, so a custom tune could help some. Log a run & see where your A/F raitos are (aka O2 readings). If you are in the 880-910mV range, & not getting any KR I'd leave it alone.
