I'm the owner of a 1994 Cobra. my mods are 190lph, fuelpres reg,73mm maf, 70mm TB,pulleys, stock cobra intake,stock 24 # jectors, bbk Lt headers, x-pipe,mac catback, crane 2030 cam,trickflow tw heads, my ? is. will i benefit from a dyno tune/chip? the car runs OK but it just feels like something is holding it back. also at idle the thing smells rich as all hell :-[, will a tune clean that up? did anybody on here feel a difference with a dyno tune with somewhat the similar setup as I?
