If not planning on the warranty they offer for sale,like others here mentioned,don't use the canned tune. If you go with a Cam and Headers through the Corsa Exhaust you definitely won't have a sleeper.
However, Eforce TVS Rotors are arguably the least whiniest of the bunch and it comes alive with headers and the right sized Blower Cam,supporting parts and Tune Would definitely suggest bigger injectors fuel pump and the JRE Eforce Fuel Rail mod if going to be adding additional mods with the Supercharger..(Oh yeah and don't forget some suspension upgrades with this extra power. At very minimum Rear Arms/Links. They will help with Wheel Hop) At 656/624 RW here now on the 3.25 pulley.
Knock on wood 16k now on the EForce. Reliable and Low/No Maintainence Put gas in it,stomp on it and hang on.
