Ok, on my 95 vert 5 speed I put in a set of FMS 42# injectors, a lightning 90mm MAF with adapter harness, a cold air intake, and 70mm throttle body. Car is running like crap now, it stumbles, pings when you barely push on the gas! Do I need a tune? Thanks

Are you sure the MAF is calibrated for the 42 lbers? If not, then that will cause it to run hella bad.

YOU PROBABLY NEED A TUNE JUST B/C U HAVE A 42 LBS MAF WITH 42 LBS INJECTORS DOESNT MEAN THEY JUST WORK LIKE THEY SHOULD. I KNOW THAT I HAD MY CAR DYNO TUNED AND THEY JUST MADE A CHANGE TO THE MASS AIR METER AND IT GAINED ME 35 HP TO THE WHEELS
