Does anyone know the actual difference in boost pressure between the g80 and g87 tunes? I have a gts black waiting to go in my car and considering just installing it with the g80 tune out the gate. Car has intakes and full exhaust, catless dps. I really don’t see how the g80 tune would hurt the g87. Of course RC isn’t going to recommend it because if they say yes and something goes wrong, they’d be on the hook for the warranty claim. Besides that I don’t see any reason why they wouldn’t okay it.

Between the 2025 G87 and the G80 base I’d say they’re the exact same. Both are making “473” hp

Anyone interested in my G80 tune? I’ll be switching to JB4 for E85 tuning.
