i have a civic and im thinking about buying a speed chip from gorillachipz. it says it gives 20-40 hp, will i get that out of it....and is there a chance it could mess up my car???
it wont mess your car up ,,but they usually don't give that much horse power,,i have used them before,and id expect to get at least 30 from it,,that's about the best they will give you,,good luck hope this help,s.
