what mods have you done? if none then dont bother, all they will do is run at less duty cycle.

Injectors are Identical, XR/Non XR

Larger injectors won't do you any good on a stock ecu.

In fact, the stock injectors are pretty good for a fair amount of rwkw.

careful how big you go with your cam on the stock ecu. it can only handle so much or it wont know how to fuel it. cms stage 3 is a good one, but my ecu made it run REAL rich, too the point it killed my cat converter and totally stuffed my plugs.

the only fix after that is aftermarket ecu.

yeah the car will be running rich cause the resistor makes the ecu think the car is colder than it actually is and pumps more fuel in. prob best to get rid of it... there are a few posts every year about these resistors and the people that post them usually get laughed at cause they dont work

if you want a good quick mod that actually works, take the air filter out, pop a 90mm or so hole saw thru the bottom of the airbox and inner guard, get some ducting and run it down to near the bottom of your front bumper, put a ram air fitting on the end pointing forward (i used a pvc downpipe fitting painted black) and get, oh, i dont know- 10 times the amount of air you had before.

oh and by the way NEVER pay 200+ bucks on a ss inductions set up when the other way will get you more air for 20 bucks max.
