whats the best way to get more power out of these v6 duratecs?

i think i imrc is a bit tempermental though...sometimes seems flat, other times goes like a rocket!

what power can i be expected to get from tuning these aswell?

cheers

 

Not a lot, convert it to ST200 spec is the best way, then decat, decent ENCLOSED Induction kit, decat, exhaust, and chip. There not a great engine for tuning
