Retuning for a bigger turbo
 

Im swapping out my 2554 for the China 2860. I know the 2860 will be flowing more air so what should I do about my fuel map? Should I jusd add some fuel across the board so its safe and then tune from there? What about my timing map? Should I do anything with it? MBC is at 15 psi and I plan to leave it there.


Thanks

just for a few rpm at a time and use MLV. It should be pretty straight forward...if you have det cans.
