Default Help with injector selection LT-1

Got a 97 Z28 with a 4.5 psi Powerdyne, 1.6RR and exhaust. Running stock 24lb and FMU. Got a tuner that will help me, also want to ditch the FMU.
What injector size should I choose?
36, 38, 42?
Which injectors are know as plug and play, no fitment issues.

Car runs real well(409RWHP), but those FMUs are unpredictable.
Thanks

Definitely get 42's...you can get them used for $200-250. Tuner can tune those easy, and you dont want to buy injectors twice.

Rich,

your car will be slow no matter what injectors you have. You have to do a driver mod.

Seriously, you can probably get away with less, but the 42#'s would not be a bad choice. I have running "green top" 42#'s on both the '94 and the '02 and I *think* 38#'s on the '01 (I forgot).

You and Ben need to come on down and meet me at SAR one of these days.
