The shop finished installing Crower Stage 2 cams and valvesprings and running it on the dyno after with no tune it only made 242hp/255tq with the A/F running rich at about 12. I'm going to get it tuned on Friday, but I was wondering if there could be a vacuum leak or if its just because a lack of tune. Will the tune bring the numbers up to at least 275hp and 300tq or is there some kind of mechanical problem?
