I have a 06 NA with the stainless works longbtube header, hi flo cat and cat back exhaust, with the weapon r secret weapon cold air intake. I feel like the car lagsbwhen it takes off, and have been reading on here about the exhaust combo that it should be tuned to get it feeling right and get it outta the gate screaming. I want to super charge it but not till later on, what do you think i should do with it. Should i take it to the dealership to getbthe GMPP tune or get a hand held tuner and do it myself, im not familar with all the tunes, but have read somewherebthat the trifeca tune unlearns??? Is thatbthe case? And any input?
