I am thinking of buying a stage 3 s4.....just out of curiousity what kind of gas mileage can i expect? and what kind of problems can i expect down the road?

 

please use search

but when done RIGHT, it is usually more reliable than the stock setup actually, that means that everything is installed properly and u use the quality parts expected for the install. either way, mpg will be about the same as the 4.2 V8, not great but meh

 

ya with mott power when installed right u shouldnt run into problems unless u drive it out the as*s your gas milege shouldnt be that great but not bad at all just dont go all out and dont run it hard all the time the stage 3 will be real nice have fun

 

Go buy a honda beater when you buy the stage 3....
