I'm sorry if this is gonna sound like a stupid couple of questions but I'm kinda a ******* when it comes down to this PCM tuning stuff. So here are my q's. I'm just put in 60# injectors on my SS but I aint got my PCM tuned yet & the car is surging up & down when I go to stop at a stoplight or stopsign or stop for any reason whatsoever. Its surging so far up & down that the car is actually shutting off because the rpms go so low. My question to u guys is will HP Tuners be able to correct this problem for me. Also will I have 2 get an Intense PCM for my car to go along with that as well.
Thanx for any help.

 

you should NOT go WOT without a tune man! you car is going crazy right now, i would take off the injectors until you get a propper tune, You could deff blow up. Dont risk it. The car is surging up because it cant level out the flow rate of the 60lbers, since you are tuned for 34lbs injectors. Take them off! put back your stockers until you get your intense tune.

 

Stock ECU doesnt run the aftermarket 60lb injectors, so a short answer yes it is manditory for you to have your car tuned by HP Tuners in order to run properly. And if I were you I woundnt drive your car at all with the injectors and no HP tune.
