I have a 88 Grand Prix with a 2.8 v6 I am wondering some ways to get a little more HP from it, the person that owned it before put 215/65-15 tires on it and the stock size is supposed to be 195/70-15, I dont understand why they did this but could this help give me a little power back by changing them to stock size?
more HP from an 88 2.8
