I noticed that there was gas in the oil so we downsized the injecs from 32 to 24s and the car seemed to run a lot better and no more surging idle either. now the car was supposed to be tuned for the 32s. will this cause any harm to the car or was this ok to do. mods are le2 heads and cam on a forged 355 with 255lph fuel pump.

 

Get it on a dyno and check the air fuel ratio, if you have le2 h/c those 24s are gonna max out, if it gets real lean you could end your motor.

 

Hope you changed the oil if not do so. Depending on how bad the gas was in the oil you could have cylinder wash if you ran for good period of time. Sounds like the program was wrong.
