I have the mods in my sig and I am still using stock injectors.do i need to go to 30s?Is it hurting me by not delivering enough fuel?

 

If you are still on your stock injectors and starting to mod I would move up to 30's or 32's. Lots of good info if you do a search. Most people like the SVO 30's and price seems reasonable. I personally like the Acell 32's. Not big enough can for sure make your motor go lean. The theroy goes that there is no such thing as too big of injector. So for you 30-36 should be great depending of course on budget. Not giving the motor enough fuel is VERY bad. I would also do a PCM tune if you move up.

 

It's hard to say without logging your car and seeing what the injector duty cycle is. You're probably close though. You can get used injectors for dirt cheap at corral.net and since PCMforless is already doing your tune you can just have him burn you another prog for the bigger injectors.

you should be fine with stockers, if you go with some ported heads then i'd consider upgrading.
