Your numbers are making more sense now. Your car won't run that great on the Microtech though. Spend the extra and put a Haltech or an Adaptronic in there. Turblown can get you an Adaptronic, give him a call and he can tell you all about its features.
Also, keep in mind a Tiger motor is an almost guaranteed bad motor so add rebuild cost if you go that route.
And, is tuning and dyno time included in that quote
. What about rad upgrade, intercooler, BOV, custom piping, fuel pump etc?
