I did my first modification this weekend - a Turner Motor Sports performance chip. I've read the threads on this and other forums about "chipping" your car, but I was a bit doubtful in my expectations.
Doubtful for no reason.
From low speeds to high RPMs, my car is more responsive and aggressive. It accelerates faster both from a dead stop and at interstate speeds.
At first I thought maybe my mind was just playing tricks on me, so I tried to distance myself from thinking about the presence of a chip and just drove the car.
It's there; more power, more response and more torque.
I'm installing a CAI this week. I'm looking forward to that even more now.
Conforti chip, aFe CAI, Bilstein struts/shocks, H&R springs, Mason Engineering strut brace, Borla exhaust, BSW/Sony audio, TMS cross drilled rotors/Hawk HPS high performance street pads, BMW style 43 16" wheels with Bridgestone Potenza P960 tires and if you've read this entire signature just to see what I've done to my car then you need some serious professional help.
If you can't afford to do it right, you definitely can't afford to do it wrong.
