Just wanted to let any Southeast Michigan guys know about Nelson's Performance. I went there today to have a speedo calibration done for the 3:73'2 and my timing and A/R played with. Dave Nelson the owner did the tuning and it came out great. 3 pulls with A/R and tune for a very resonable price. The two other guys in the shop were cool and I plan to go back again for future tuning or work that I cannot handle. It's hard to find good shops these days so I thought I spread the word.
