That’s not to shabby to be fair, I can cope with that. Worth while to get it squared away, would be upwards or the same buying a pcv and doing the same!! More research needed I think before I decide one way or the other.
Potentially the only thing I may do if the Ramair pisses me off is revert it back to k&n or something, big fan of induction roar but never had it that close to my head hahaha
Anything paired to a stock header, single muffler, cross over, 6 cans or 1 can, whatever, is going to safe but a little lean with penners tune. It’ll be miles better than stock tune even, which is garbage.
If anything, you’ll need to pull fuel under 2000 RPM and add over 3500, but it’ll be fairly close.
The problem putting the full header replacement tunes is going to be low throttle and mid range and full power over 4200 RPM. The after market headers are going to scavenge a hell of a lot better, as such the fueling will not match stock header + custom slipon at all.
Ultimately though, strapping various things on stock headers is going to need a custom tune because the Triumph TORs tune.... is also crap.
