So I just threw on a supercharger for my car and everything looked great. Installed the tune and started it up. I'm like ok, runs fine, no leaks, idles fine with 19 inch of vacuum so there's no vacuum leaks. But then I go to drive it to work and stalls 3 times, drives like crap, and throttle response sucks. From a dead stop it sputters and doesnt want to move. Dont know if tune didn't get installed correctly or what's going on. List of mods. S/c, intake manifold, lsj throttle body, 60# injectors, 2.8 pulley. Other stuff but will tell if need to. If anyone can help that'd be awesome.

 

More then likely its the tune.

And the 60s r shitty injectors.
I would recommend finding some 42# injectors

 

I hope its just the tune. Gonna reinstall tune when I get off work. But I thought you needed to use 60#'s when running the 2.8 pulley.

 

Na i tuned becks le5 on a 2.9 and the injectors were only at 75% by 6750rpm

 

I think that's probably what the problem is. Cause it feels like the engine is getting flooded at low rpms, once I get moving its not too bad

 

I thought you could get tuned for the 60#s as well. I've hears other people run with them no problem. I got my tune done by vince st trifecra

 

i don't know where the OP is from but the le5 on a 2.8 with 42's will not be happy in low elevations and temperature below50f. Maybe a summer only tune on the lean side will be ok...

 

lol(:

so you only put 1 tune on the car? no revisions no nothing?

 

Yea. I know I got to get more updates for tune bur I thought it would be at least driveable for first tune

 

More then likely it's in the tune.

 

Idk, guess ill send them the datalogs that I could do and see if they can fix it. Thanks for the input guys
