I just finally installed my tune from MadZ28. (just in time to put it away for winter ) Right after it finished installing i took it out for a quick drive to see how it was. well, under slow acceleration its fine, but as soon as i give it just a little gas it starts severely surgeing and makes a loud sputtering noise. It feels like a really bad missfire or somthing. I already sent them an e-mail, but i wanted to hear what you guys think as well.

thanks for any imput.

 

Anything you may have forgotten to tell him like non-stock MAF or injectors?

 

also, anytime you have a problem with a tune its important to notify them asap.

 

Never had any trouble with mine or heard of any. Thats crazy, keep us updated.

 

sounds dumb, but check fuel filter, maybe just coincidental that the element colapsed the same time you installed tune.

 

Still stock MAF and injectors, the only thing that changed was now there isnt a cat. Think that couldve made a difference?

I did notify them as soon as it happened and havent driven the car since, havent heard anything though. Figured that since it was on a friday night, i wouldnt hear anything till monday, thats whyi posted it.
