Pretty much what its says. From asking around most of my problems seem to be in the tune. Looking for a good tuner somewhat close to north Alabama. Car has a built bottom end, Procharger D1sc 16lbs and supporting mods. Right now the car puts down 525wrhp but stutters between 2000-3000. When driving around town sometimes when you nail it it takes off great other times it seems slugish and lacks power. When I put a slick on it falls right on its face and will only run 103mph out the back door. Mind you it will run 118mph with street tires. About 5 or 6 people have been tuning on the car in the past 3 years. and no great luck luck yet. I am out of the right now counrty this is the main reason why im trying to keep it close to home if posible. Any great sugestions?
