Regals gs
Hi, I have a 2013 Buick Regal GS and I recently modified it I put a K&N intake and a zzp down pipe and now i have a engine light on, does anyone know what is the best tune I can get to up the power even more and get rid of the engine light at a good price? Also is there a tune or mod to make the car pop when downshifting?

Not sure about making your car pop when downshifting, but if you want it to pull I can vouch for the Trifecta tune. That with the Buick Stage kit really woke mine up (non GS).

I agree with teebore, I have the Trifecta tune and it really wakes up the car. You will need to have them remove the O2 sensor monitoring so the check engine light won't come on.

As for the popping you seek, you need to remove the mufflers & resonator for this to happen. The mufflers suppress any popping sounds from the exhaust, but as you know they also quiet the exhaust tone.
