034 stage 2 E85: violent jerks under WOT and AMAX shifting

[tcasas209]

Bit of a concern here: has anyone on stage 2 e85 experience violent jerks under WOT? It happened around 3rd and 4th gear.I felt like it was my diff tripping out. But after I left off the gas it was fine. No smoke or leaks near the diff at all. Also not sure if AMAX Shifting had something to do with it. It was about 60 F outside.

Have you emailed 034 support? That’s the best place to start. Since you’re in their neck of the woods, you could also book an appointment at their service centre to have them check it out.
