Every car technician at Power Tech is top notch. When you've got a $60,000.00 investment, and then throw more money into mods, you had better put the car in good hands. They get work from auto dealers, and also work from customers who were disappointed by shops that did sub-par work.
Back in the day, Rob Downing did the n20 tune on G1 at FordSpeed (yes, Fordspeed). Dino was my car chief on G2 which became a test bed for Vette stuff at RevXtreme. G3, G4, QuickSilver, and Ghost 13 were all tuned by Jeremy at Fasterproms.
BTW, Jeremy's "Jeckyll and Hyde" tune had QuickSilver so stout, I slapped a CL550 AMG back to Berlin with no problem. Old 13 was faster than one might think. I wanted Murder 1 to have the super power and incredible handling with the attitude and bitchiness of Old 13.
