These kits are set to a power rate, witch does not cause excessive stress for the stock engine. You can expect about 50% power gain, with excellent mid range response. We measured 200-210hp, it can produce boost from 2000revs, and full boost (6-8 psi) is available well below 3000revs. This kit is our choice for an excellent daily driver. You can raise the boost with an aftermarket boost controller, but it is not recomended by C2power.
