I don't know my whp right now...I have to guess around 170-180 or so with the way it feels. It was worth it for sure, to have everything already there.I have had a few issues, but small stupid things that were fairly easily corrected. For instance, the L bracket supplied to mount the RRFPR to the head was fine, but the tiny bolt used to hold the RRFPR itself broke 2 or 3 times. I finally said forget it, and relocated the RRFPR right under the AFM/air filter, and made my own steel bracket to hold it down. It's been much better and fine ever since. That's about it though to be honest. I had a crap idle issue, and I narrowed it down to the ICV. I didn't want to spend the money for another one of those stupid things, so I got a slightly longer bolt to hold the throttle open and see idle at around 900rpm. Actually, this car has always had an occasional crap idle, and more recently it had started to either nearly die or just die when I didn't have any pressure on the throttle.This really helps with the A/C on, since I also have a UUC 11.5# aluminum flywheel and e34M5 clutch, and it tends to make all kinds of fun rattling noises at idle, that are now nearly gone with the higher idle. Overall, it really has never run better than it has recently. Though with track events coming up next year, I think it's time to replace some things, and just get done with basic maintenance things (fluids, etc) that I need to do anyway. I guess boost is around 7.5-8psi, and actually have a vac/boost gauge on order and gauge pod as well. I will also be getting a wideband o2 and gauge to monitor that.Oh another issue that is unrelated to the DASC itself was that my IE polyurethane motor mounts outright failed on the car, so I went with OEM Lemfoerder parts, so I don't have to worry about it anymore PS: Here are a few older shots...beofre I did a few other things (like relocate the RRFPR for instance). Sorry they are terrible cell phone pics. I desperately need to clean the engine bay up when I get a chance.
