Fast 102 and injectors
I have a 2007 base but have a few goodies.. cam, exhaust, cai, headers and a tune. I wanna get a fast 102 and bigger injectors. How much can stock ls2 heads handle? What injectors are an easy swap without replacing the fuel rails? I just want to do an easy swap without too much of a pain in the butt having to spend time and money replacing parts. I did research but couldn't find enough info to make a move. Thanks

you will need to get a retune after adding the FAST. what percent duty cycle were your stock injectors at during the previous tune? You might not need bigger injectors even with the intake swap. If you do, FAST sells injectors, they will hook you up.

The duty cycle was 92%. I called Texas speed performance and they said the same thing. Get it returned and he recommended to get 42# injectors. Just wondering how difficult it would be to do it myself.

Injectors are very easy to change BUT you will need a tune. Better to drive to tuner on old injectors and let tuner change them. Don’t drive on them untuned.

FAST injectors are ****, no data available as far as I know. Better to get some factory GM injectors with real data available instead.
(I prefer ID's but they are probably overkill for this situation..)

If you need injectors stop by our site or give us a call. We have tons of options and great prices (discounts for board members). A set of 42lb injectors would be a good start but you will need to get your car tuned for both the injectors and the intake. You really shouldn't even drive a car after doing an injector swap without handling the tune first. If you're local to us we can do the install and the tune fairly cheap.
