How did you find that out? Makes me want to check mine, just in case.

IATs were high according to my P3 gauge and I don't hear the water pump anymore when i have the car on accessory mode. it's usually a pretty audible whirring sound. hoping it's a simple power connection issue.

Might be a popped fuse.

I had a coolant leak issue a while back that I caught pretty quick, but I think my pump ran dry for a few miles. I don't know if it's possible for that to have damaged anything, but since then I've been extra diligent about checking the coolant level and making sure I can hear the whirring noise in acc mode.

fuse is fine. could be that the water pump failed, at least it's only $100 or so. i'll update as soon as i figure it out.

Sorry to revive an old thread, but I couldn’t find my answer anywhere. Does the canned G1 tune from ESS handle the forward x ok? Or do u need a custom tune for it to run right? Asking because my NA stage 2 tune was diff for the forward vs standard x location. Trying to decide If I want to keep forward x, because I don’t want to go custom tune route once I install the G1.

Added cats and change the X pipe location - awesome net gain, espcially under the curve.
