RPI scoops? Very good mod...Pulley's very good as well...ecu? Not for me. But most people like them, better shifting (SMG), higher redline, increased throttle response, minimal hp gains. Pulley's and RPI definitely worth it.

Rpi, Evosport pulleys, and ecu remap. what gains am i gonna get with these mods. Anybody had these mods done??? are they really worth it???
Gains will depend on the dyno, because dynos do vary a bit, as do dyno operators and dyno conditions (what kind of fan is used, the air temp, etc).
We've seen on average 10-15 hp gain to the wheels on the RPi scoops. If you dyno using a seriously high powered fan (like Dinan uses, or a Dastek, or Cincinnati Fan HDBI), the dyno will show a greater increase in power. There's a few hp additional gain if you switch out the stock air filters to BMC.
For our pullies, we've seen roughly 15HP gain on a DynoJet inertial dyno. Some have reported more. The EvoSport ones are not quite as light as the RPi ones, but they're close enough that the HP gain should be very similar.
In terms of software, we haven't seen very much gain on the 500hp mode. BMW really did a great job, IMHO, given typical gas quality/formulation in the USA. You may gain 8-10hp or so more from software with respect to a stock or near stock car. The main improvement is in shifting feel, throttle response, delimiting, raising redline, etc.
