So did you get rid of the FMU and get the 36# injectors????

 

yes..i took off the fmu and put in the injectors...

 

Take that thing to Bryan at pcmforless.. Programmer@pcmforless.com

Hes in your area and will get you straigtend out

 

My car did that after I put the supercharger kit on. Turns out, the positve/negative wires were reversed on my inline fuel pump. Switched the wires and it ran like a bat outa hell..

 

thanks alot guys...i will definatly get ahold of brian because i think its tuning...and also i will check my pump over because i installed it

 

You did have the PCM programed for the #36 injectors right and got ride of the aftermarket maff? If ya did good. Bryan will take care of ya from here on out..
