no, the fpr is good actually...

example, if u chg ur exhaust system completely, for sure u hav done sumthing to ur car right? by tht time, u can say u hav chg the exhaust not to its default setup with ur car..

maybe u nid more or less fuel to make ur car can b on its full potential with ur new exhaust setup...

its slightly useless imo if u use fpr without modding anything to ur car..

thts y i said nid the expert to tune it for u.. if u set less fuel than ur car nids, thn gg to ur car lor...
