I am not sure here but it looks like I can get this without changing the pulley size. Correct me if I am wrong, but what I was thinking was going with the 42# injectors and stock pulley with this PCM.

Opinions/suggestions please.

 

not bashing ZZP by any means but the last person with this canned tune had some of the worst AFR tht iv seen. almost to the point of blowing his engine up... i would just get a proper tune.

 

^^^ Agreed. I have not really heard to much good come out of Canned Tunes.

 

Bump...I thought that someone from ZZP would have chimed in by now.

 

You are better off getting someone in your area to tune you with hpt.

 

ya canned tunes are just that canned as in through them in the can. just get it done right

 

That is part of my problem. I have tried several times to find someone within reasonable driving distance that can tune Cobalts and was unsuccesful.

Can I drive the car with the larger injectors in any distance to get a tune or will it mess up the car?

 

In theory, if you stay in cruise, don't go wot and be real careful you can. I don't know about going out on the highway... Its all afrs really.

 

too busy with headers and downpipe issues.

 

the only canned tune i would feel comfortable on, are the GM tunes.
and even then its questionable....

 

I see your in PA, pm WickedSS2005, he has tunes 95% of the ohio cobalts about the surrounding states. Hes tunes my car also

 

that is my concern. if I am running too rich, I dont want to blos something up.

 

Well, when people get stage 2 installed, it states it is safe to then drive the car a short distance to a dealership for the reflash...
