My plan is to just replace pulleys without ECU and see what happens...
Least expensive is ASP Racing. They have an 14% overdrive pulley with Dampener (same as renntech and EVO) for $970 - No ECU tune - keep the stock belt - easy bolt on (with a big torque wrench).

Ask for part number 331380 (not listed on their website) Here are the pics they sent me.
Then there is a new kid on the block (leading edge technologies) that makes a 20% Overdrive Pulley - but you need a new belt and I found no way to contact him, email, snail mail, phone or fax. Heck I can't even find their website anymore.
And then there is EVO - similar to Renntech - they offer a pulley kits with and without the tune - and with a harmonic dampener and without one.

Scroll to the bottom of the page for the kits for our engine.
Good luck and let us know what you decide and how it works out.
