[QUOTE="Pat Freeman, post: 614846, member: 55026"] This won't void a warranty unless it is proven that it caused a problem. You can re-flash back to stock, so it will not be an issue. PRM - the 87 tune has been giving me worse gas mileage than the stock tune. The 87 tune keeps the ST in gear longer, which is nice, rather than shifting immediately. I'm seeing high 13's MPG in the city and about 18 MPG highway. [/QUOTE]
