Looking for recommendations for someone who can diagnose a highly tuned car. I have already been to the 'name brand' shops out there. Any help would be greatly appreciated.

I used Tuning Technology out in Farmingdale - ask for Bruce - He does alot of highend modified Benzez

i have the perfect guy for you... his name is jeffery and he works for rallye benz.. he works either out of his house or he works from rallye after hours.. he is really good and really fair priced 516 551 3214 tell jeff mike with the audi rs6 from bullrun sent you

Chris @ Auto Addiction...Lindenhurst. He's the best, only works on modified Benzes.

True that. The fastest E55 on the East coast was put together by these guys ^^^.
