BPC Tune Stage 1 Added

Installed it last night, my car is all stock on the powertrain front except for a 135i muffler swap and golf tee mod. Purchased the BPC tune a few weeks ago when it was on sale. I plan to add a 3 stage intake manifold and maybe an intake at some point. Not sure on headers, likely not.

Anyway, first impressions are the car is more responsive for sure, dead spot in some situations on low throttle is gone. Car generally feels more muscular all around, so I'd say this lines up with the mild prediction on power increase (10-15hp or so at the crank).

Now looking for a good deal on an 3stage IM....

One curious side effect, the car doesn't seem to have the burbles on overrun as much anymore...used to get a gentle pop around 2500rpm with the revs on the way down...maybe the leaner mixture in the tune cleared that out.

I plan to dyno once I have all the mods in place, was thinking about doing it at each step but that's money I'd rather put into the actual parts
