the only reverse technology i use is to get off the driveway in the mornings:p

I'm using 0.5mm oversize pistons so I guess I have 8.7$:1, hope to gain more power with less boost pressure & lag....or it might blow a hole in a piston :confused:
Tested the mileage again and it's come out at 36mpg so i think it's helping the economy a bit
