Hi all I'm new to the community but I am an original GN owner since 87 so I have looked through this forum for years. Anyway can anyone recommend a good ECN-GN tuner in the local Detroit area? I'm looking for a local shop with a dyno that can review my current tune and offer up expert advice on things that should be changed. I need help finalizing my 93 and alky tune and then plan to switch to E85 after that tune is correct. I really like the ECN-GN computer which has forced me to better understand my car. I believe I'm on the right tuning path but by no way am I an expert. Any help would be great.
