- brown plugs tells me that there is something in the fuel that should not be. Did you use any kind of additive in your fuel? If you did, I assure you that is the problem.

No reason to change the FPR unless you plan to break the 400hp mark.

I use only 98 or 100 octane fuel without any aditives.
The plugs are ngk bkr7e
walbro fuel pump, also tried with bosch pomp (the same)
The mapping is horsham stage 1
And it doe's not feel like 260-280 hp
I don't know what else can be wrong.
