so a couple of months ago i bought a used 2002 A4 1.8t, with 50,000 miles on the engine cause it was replaced. i havent really done much too it besides a new filter and forge dv. i plan on gettin new wheels and so on once i get the money. BUT i plan on getting it chiped and was wondering which companies offer the best ones. As of right now i am going with the APR 1+ but im starting to read alot of bad shit about APR. so need some advice. Also was wondering if the spring in my dv wud need to be changed to a stronger one. Any help would be greatly apreciated, thank you.
