here comes the kicker that I found out about. Due to no fault of anyones, upgrading to the stage 4 requires a complete reworking of the fuel and air sytem as well as of couse the turbo, and exhaust manifold. The idea here is that if you have the stage 2, you would either want to choose the stage 3 or the stage 4. That is like when you buy a K04 kit and went to an APR stage 3 you would have to scrap all of the suff you bought previously related to the turbo. Good question. cheers! Mike
