A simple solution to more boost other than bleed valves.
Simply pack washers between the wastegate actuator holder and the mounting. Please be very careful with how many/how thick you use, be sure to have a boost gauge handy because if you pack too many in there you boost will go fairly high and the computer will cut in an give you the CHECK ENGINE light. Usual max boost is around 12psi before the computer cuts in and says overboost.
As far as i know this is do-able with both 2.4LT and 2.4LTE models as the 2.4LTE model will compensate for fuel electronically, depending on the boost level, and the 2.4LT has a fuel regulator which changes fueling with boost.
PLEASE NOTE:
For best use of boosting your Turbo it is recommended to have an aftermarket exhaust system to help extract the hot gasses quicker, as the stock exhaust system and dump pipe are fairly restrictive and your turbo will find it harder to boost to higher pressures.
