Best I can tell your right on the money. Anyone tuned a BF and got bugger all??? ← Autotecheningeering got a hold of my BF xr6, put a set of paccie headers and 2.5" stainless exhaust and pulled 154rwkw on a dyno dynamics, went back for a tune a couple of months ago and grabbed another 15kw from it for a total of 169rwkw. quite a healthy boost over standard.
