Will I need a tune If I put Kooks longtubes , Corsa touring exhaust and a K & N air intake system on my 2008 Trailblazer SS will I need a tune or will the factory computer handle these changes?

I think it would be fine without a tune, you would just though some ses codes. but if you dont plan on getting any more mods for a while i would get a tune cause youll get a lot more horsepower out of it. I could tell a huge difference after my tune wheni got headers

I would spend my money on the tune... It really wakes up the TBSS, our trucks have a very conservative tune from the factory. You might wanna check some TBSS sites they have some good info on the trucks.
Also check into making your own cai. Only thing is when you remove the factory "neck down" after the maf you will NEED a tune.
