Great product for my stage 3+ B9 S4 Pure750

Installation went very smoothly. Had a TPMS light after install which was cleared with OBDeleven. Runs strong as expected. Customer svc/tech support top notch as has always been the case

Fantastic

So nice to have this option. I honestly think the tune runs better now through the FlexFuel programming. I am HPFP, FMIC, DP, intake so I think IE calls that 2+. Update to app was seamless as always.

Couple of install notes for B9 S4: when adding the two fuses that go into the fuse jumper, these are extremely stiff. The fuse jumper dose not fit well in the dead pedal fuse area and make sure you trim fuse box side to help this process accounting for wire leadout. When tying into the main harness, take your time. In retrospect I would have used a high quality vampire connector. Once you cut the harness wire, it is under tension, and therefore will no longer be long enough to reconnect and then you will be soldering extensions on.
