Not sure who tom and brian are? The shop I'm thinking of is run by George ReggioMaryland Performance is a great shop. No aurgument there. The owner Tom and Brian have been great at supporting local racers.
But there are more Chevy focused and I don't think they are Diablo and SCT trained. RevAuto specializes in Mustangs and he has a dyno right in his shop. Knowing both shops, I would still book time with RevAuto for this issue.
Just my 2cents.
Would definitely be interested to hear, I'll PM ya.Chiming into this a little late, but in short if you haven't found a tuner yet JPC in Millersville, or even Booz Brothers Racing in Marion PA also have good reputations. Horsepower by Herman is also a tuner in Maryland and has been doing Fox Bodies for decades.
Personally, I would stay away from Maryland Performance Center. Been working with these guys for years and have had more issues than success, and have spoken with others who feel the same. PM me if you want further information.
