the best tune for the money i found, is installing 170 thermostat, disconnecting the TCC function in the trans, pull out the restrictor in the CAI, and activate the power enrichment in the ecu. this alone will trip the Torque management so you know it makes good power for cheap. total cost about $250 and almost adds 20 hp , requires premium fuel to keep the engine in the high octane advance table, next power upgrade is the E85 sensor, might add 10 hp
