I just got in my 90mm MAF today and wanna put it on. I have a 99 L and was wondering if I have the same injectors as a 2001? And will it hurt to put it on tonight without reprogramming my chip ? Please quick input suppose to go race tonight ? thanks alot

 

It won't hurt it if you HAVE to drive the truck short distances... but you definately need a chip reburn before you run it hard... just my $.02

I wont do it then b/c there is no sense in tearin it up thanks alot for your help!!!!!!!!

 

more air needs more fuel, or you have a lean condition, how lean...don't know. Would I take the chance, without a reburn?NO
