the revs hit 3 thousand and then the engine keeps reving really slowly or not hardly at all and receives no output, it was takin to black mac performance today and they fixed a exhaust manifold leak of the turbo but they said everything like fuel air ratio is fine, I drove it home and it hasnt changed and it is driving me insane HELP PEOPLE, it was origanlly tuned by xtreme ford about 6 months to 294rwkws but hasnt seen past 3 or 3 and half thousand revs for a while on the road, even though on the power run on the dyno all seemed fine, maybe the tune has run dead ?????
