I am/was not thinking about radical changes that would turn the car into a hot rod. That is, NO cams turbo/supercharges etc. I am grandpa (67 years old) and simply want a tip top daily driver.
My main desire is to correct any de-tuning that may exist to reduce emissions. The things I see on the internet seem to be parts that claim to alter the computers operation.
Is the engine de-tuned for emissions? If so, are there any parts available that will re-tune the engine for better performance?
