BFI Stage 1 PEM - MK3 / B4 2.8l VR6 OBDIIThe BFI OBD II VR6 PEM is designed to not only increase power and throttle response, but to also smooth out the power as it is delivered throughout the RPM range. The Stage 1 VR6 PEM offers noticeable performance gains over stock on the torquey VR6 engine. Carefully mapped adjustments to the fueling and timing allow the most to be extracted from VW's VR6 powerplant. The PEM also increases the rev limiter to 7,000 RPM and deletes the top speed governor

Sizes run small; larger sizes not available
I returned the jacket because the size was much smaller than described. I liked the look and feel of the jacket and the material, but b it x was v much smaller in size than a different jacket I bought at c the same c Times in the c same c size from b a a different company. The other b one for me v perfectly. The Coofandy jacket was not a standard size and much much smaller than I had hoped. If they had offered a larger size I would have exchanged it for a size larger. But they don’t, so I returned it and kept the other one that fit like a glove.

Not for me
The item was too small although I went by the size guide. There is also some uneven white stitching on a gray garment
