I want to fix my idle problem

[NSXPOWR]

I want to fix my cold idle problem. Most say the problem is in the factory chip. I've tried all the adjustments like resetting the iac and tps. Can I put a thrasher chip in my stock gn? All stock fuel system. This is my girlfriends car and she will not drive it much in the winter because of the car stalling when cold when put in gear, until it finally warms up and then everything is fine after that.
Thanks, JOHN T.

You can use any aftermarket chip as long as it's for a stock setup and 93 octane gas. The stock chip had a problem with the idle when the car is cold and most aftermarket chips work a lot better. The Thrasher will work fine and is an inexpensive chip.

The Thrasher requires 45 psi baseline pressure setting. Make sure you are getting that if you dont have adjustable FPR.
