OP...dude this is hard to read, for a guide you need clear sentence structure, it would also help if you didn't confuse things with the references to several tuning solutions that have little to do with our cars.
If you want, you should cover each offering in a separate paragraph and draw conclusions at the end...also the Autocross blurb was near useless given that the only data you gave was rounded off to the nearest whole second...and there was no delta...
for the effort...I know it is time consuming
