Noticeable economy improvement
I installed the stage 2 performance module after installing: Airaid intake Jet throttle body spacer Mishimoto 158 degree thermostat Msd ignition w/ vms 10mm wires JBA cat4ward headers & dei titanium wraps The module has really made everything play nice together, and I'm seeing about 30% increase in fuel economy! Well done, Jet! The only reason I gave 4 stars on installation is that you have to remove the air intake and power steering fluid reservoir to get the module to fit.
So far so good
I've only had it on the car for a couple of days (2005 PT Cruiser Turbo HO) I did a number of things at the same time. MagnaFlow cat-back exhaust system, K&N intake system, Throttle body spacer, Pulsar plugs, MSD plug wires, Screamin-Demon coil... The car runs much stronger particularly noticed significant gain in the low end and transmission shifts are much quicker (auto trans). The cat-back system is a little louder but not annoying. To early to know if any MPG improvement. Feels like more HP
