this is old news to me but basically there is some speculation that the evo was tuned for the crappy 91 octane CA gas.

also some "press" cars were dynoing at the "correct" whp... so who really knows but Shiv (owner of vishnu) is in contact with Mitsubishi to get at the bottom of things.

Shiv is also the one that found out the 2nd gen Miatas with the 1.8L engines were not indeed putting out 155hp.

so it's actually a good thing IMHO


EDIT: keep in mind he still have a small sample group. I believe less than 10 but one of them put down 189whp with 91octane.

also his dyno is extremely accurate and posts less hp than other dynos, mustang/dynodynamics(sp?), dynopack, etc.
