Not aware of anything ever even mentioned here (one related thread?) on chips and tuners currently available. These are by far the safest and best upgrade for the money over anything else. In the old days advancing the timing made car noticeably faster but drawbacks were hard starting and running a little hotter.

Maybe not, but as example that car has a silver key and a red one. The silver key is for regular and street driving. The red key is for drag racing and/or track racing, completely changes engine parameters. So of coarse that's the key I use all the time but could switch back. Do like how the car shudders and rocks at stop lights and engine running choppy (4 camshafts, hmm).
