Just a little background on my car...05 MCS mods include: JCW Intake/15% Pulley/Cold Plugs/JCW Software. I took the car out for a short spin and can definitely feel a difference. Since I havn't had a chance to drive a JCW car I couldnt give you a comparison. But this car is damn quick! It would be nice to Dyno the car just to see what it does. The next logical upgrade would be injectors.

I think it still might take a bit for the ECU to learn my driving style. I just drove a stock 04 MCS a few days ago and driving both is like "day and night" I am glad I upgraded from an 03. Once I have a chance to put a few miles on it I will update the thread.

Let the fun begin

 

How much was this?

Did a dealer do your reflash, and for how much? I have almost the same mod's and have been looking at the MTH or GIAC. I had not thought about using the JCW.

 

Actually its not for sale.........I know people that know people Its more like an experiement......
