Unless he has the tunes from Phil at BOE, and I live in CT, he is full of SH!! because I know of no tuners in this neck of the woods that can deal with the ECU. As we all have said, for street you can have it tuned for a BIT more. You will not find it very beneficial for track as heat soak will neutralize any gains. It is a mid 4 second car, you are not going to make it that much faster and will basically just kill the driveability as you are discovering. Your "tuner" sounds like he has already Fu!!ed things up. He should already know the SC is at 90++ % of its potential.
The S is one of the smoothest power delivery vehicles I have had seat time in. I know what I can match down a straight on a track...as do the folks that can't walk me...nothing to do with driver...just straight away power. The car is very much respected. It is not a street racer. Its a Lotus , Take out the 44+lb exhaust, install an 18.4 lb 2bular. Take out the 40+lb battery, install a 3-6lb Li. BOE CAI, Right there 70+lbs =7+hp and better handling. Rotors, lighter wheels, remove +2 or +0 crap in the back...it all adds up. 100lbs = 10HP. That is what each iteration has done...make it lighter.
