I was curious how good the JET computer upgrade is, like is it worth the 300 bucks. And I was wondering if I have a boosted car running like 11 psi and want a new computer would JET's upgrade be enough or should I buy AEM's management system for 1500 bucks???

if you are boosting, then getting the AEM management system would be better. But from what I have heard, doing the JET upgrade doesnt really do much. On our cars it wont do much, maybe give you a good 5 HP. For our car, every $100 you spend, you get 1 HP, now for cars like the WRX, for every $15 you spend, you get 1 HP.

Is there any type of computer upgrade that I can get that will give our cars a good increase in power, I know that OBD-2 systems are a lot harder to upgrade than OBD-1 but it can't be that much harder for a big company like HKS or Greddy.
