Ok so a set back.. I went to have the water/meth tune done and we did a base line run before the new tune a/f looked good no knocking but hp on the top dropped off by 70hp
On a compression test 2 of the cylinders on the driver side were low we were thinking head gaskets ok hoping head gasket So the motor is out of the car and taken apart looks like a piston ring was casing blow-by so I am forced to build the motor with a .020 over bore. Going to drop the compression by 1 point to a 10.5-10 cr Man I was not rdy for this good thing I have my zx10r as a back up Down side I have to drop another 6k to have this done ![]() ![]() Ps : and yes the plan is to use the on/off switch to switch between tunes One aggressive tune for water/meth and the other with out w/m.
