Recently got Pure Stage 2+ turbos installed on my F80 this week. Here's my dyno run:
With the exception of downpipes, this car is otherwise completely stock for performance upgrades. No fueling pump upgrades, no meth, no PI, nada. Just running an OTS BM3 Stage 2H E30 tune.
I plan on getting an E50 custom tune through PJT in the coming weeks, at which point I'm hoping for more like ~650 wheel. However, about 600 wheel is how these cars appear to run in a pretty bare-bones build with the one-size-fits-all 2H tune from bootmod3. The guys at my local performance shop tell me that the OTS 2H tunes leave a lot of power on the table, and I'm inclined to agree.
I'll be running it again after a custom tune!
