One other tip,,,, I always recommend,,,,use a progressive methanol injection set-up.

You get high octane methanol injected into the engine,super cools the intake charge,,,always a great idea especially since you are not running an intercooler.

This is about the lowest price I have seen for a progressive system.

My friend has the same basic system on his 1.8T Jetta,,& it works great!
