Once I upgrade my MAFs and retune, everything will be great, but so far I have no complaints. I'm in hot South Carolina now and have been doing some hard highway driving; temps haven't gone above 200 on the factory Oil Temp guage. I've got a Stillen Gold Series oil cooler, Mishimoto radiator and thermostat.

Driveability has been awesome and the power increase feels great. I love the whine of the supercharger. People tend to have a "WTF"/perplexed look on their faces when I drive by....they either think something is broken or they know whats up.

I've got a 1500 mile road trip to TX tomorrow, so we'll see how it holds up while driving across 5 different states. My dyno sheet is posted up in another thread by Motion Lab.
