a guy on the source had same issue, they had to make him a recovery file.. and Gus had to get him a new tune.. I went with American Muscle Bama tune.. worked just fine for me..
found you again steve :P... from the other forum... any who, i took your advice, got the SCT Tuner, woke that car UP.. also put on the Bassani exhaust.. man..... i loved the speed 3, but damn this puts that car to shame.....
even if you get that much power, its still slow.. 5k+ for that, total engine rebuild, port polish, big turbo, then the motor will still prolly fail on you..
Fail dealers... See if they will align your mazda emblems on the rims to.. make sure they are always aligned when you stop and park the car.. if not, bring it back to the dealer..
build up the motor, and you can get decent power our of your 2.3l, you wont have the head aches of DISI, since you still have Regular injection, pop some bigger injectors in, with stand alone, 350whp all day long..
