Jeff is good for stock work.
He wont touch porting or performance.

He will send you to Scott.
I only had one of my 7s at Jeff shop and that was over 5 yrs ago.Scott tuned it and I have to say.I was not impressed at all.

I found my way around my car better and ended up tuning it myself.

Be very cautious who you take your car to.Theres alot of rotary "mechanics" out there.

Post up what car and what kinda work you tring to get.
