Local dealer has a couple of CVPI's on his lot. A pre-flex fuel model and a flex fuel model. I'm looking at going the FIPK, bigger throttle body route. Would it make a difference between a flex fuel and the non flex fuel. Obviously the flex fuel model is newer. I'd prefer a newer model but not if I can't do any mods to it.

 

The flex-fuel models upgraded the fuel lines to stainless and other parts to handle Ethanol. You can do the same mods to either model.

 

Thanks a lot.
