Hi guys , I have a black / blue '09 R and was after a little advice.

It has a barnett 2 into 1, witch I run with the baffles out most of the time . Stage 1 K&N and a pcv. I had it mapped at serco with the snorkle left in - the induction noise was giving me the !@#$s . A map was made for baffels in and one for the exhaust baffles out and I run a map switch .

I have a DNA stage 2 filter on order and I was wondering if anyone had any advice on modding my fuel map to allow for the extra flow? Add 2 to the value on every thing on my fuel table mabey or is it more complicated than that?

Worst case i'll spring the coupple hundred for a retune but but I'm cheap.

If any more info is needed just ask.

Thanks guys, any advice is appreciated .
