How close were your dyno pulls (were they back to back)? This seems like a fairly basic concept that is SIMILAR to the cold air packages they use for the vettes (only the vettes put an airbox on top of the area the "VIPAIR" covers. To me it seems that a lot of his other stuff is kind of a "knockoff", but maybe this piece will work. A while ago I ordered his guage pod for the B pillar and it didnt fit at all. LEft a huge gap around the window frame, it didnt seem like it was made for the viper, so I havnet ordered anything else.
