Been searching around the interweb for performance related parts for the Nissan Altima Coupe. My HLSD will be done any day now. I have FK-Ethos rims and 235/45/18 tires on the way, as well as Racing Line Performance STS. Anyway, I have stumbled upon the JET performance chip for the Altima qr25de. You actually send out your ecm (PCM..whatever you prefer to call it) and they solder the new chip in and tune it for you. Does anyone have any input on this product?

Jet is cool,the down time is while u ship is bothersome

Valid point. I'll wait it out. I dont feel like being without my car for a couples weeks just to gain a couple h.p. Ill wait til I boost it. Thanks for the input!
