I think it may be possible depending on the car, and it's mods. Mine was stock mid-pipes, just the magnaflows, then I installed the bbk x pipe and headers, I dunno, regardless what the Gtech said, as I know from experience they can be off on the MPH often, my car certainly gained more than I ever thought from the pipe...it's just weird no way to explain. At 4k rpm it wants to break the tires loose in second....it's like...out of no where I get a boost of power. I dunno, I need to get all of my other **** installed and then get a tune, and then go from there. Right now it's basically stock it doesnt really matter, I was just really suprised at what an O/R X-pipe did to my car.
