Hey guys so I attempted to tune the Grimspeed BCS the other day and I basically gave up and put back my MBC. Every gear except 3rd would boost over 30psi, 3rd only 20psi no matter what I changed. I read both threads on tuning a 3-port but I had no luck at all. What could be my issue? I'm pretty sure i installed everything right, I left the first port without a line since I don't have a stock intake to route back to. Please help I would really like to get this working.

Thanks guys

Evo Kid, did the GrimmSpeed BCS require significantly less WGDC than the GM for a good result? I would like some feedback and numbers for the guide if possible.

Ahh dude I'm in the office send me a pm with a screen shot of all your boost setting. Maybe there is something your missing either in your tune or in your setup of the solenoid. BTW what are you trying to run Load or direct boost? Either way when I get home today I will help you out.

I never had the GM solenoid I just read some reviews on the GrimmSpeed and saw a few tuned first hand and I have to say it was nothing short of amazing. Actually my tuner who was a little bit skeptical about it would have prefered a buddy of mine getting either GM or Peirburg 3 port. But after he tuned his car he said he loved the Grimmspeed and moving forward would only suggest that for all his evo customers. From that I bought one for myself and tuned it. I have had no problems with my boost since then.

Here is my review

Hey guys thanks for the help, I havent pm'd anyone because I currently dont have the BCS installed and cant make any changes till this weekend, here are my setting, anything that I would change wouldnt really help, even Zero-ing out the TBEC table

Uh your BCLO is too high. Remember you add BCLO and BDEL that is the final load base that your ECU will try to seek. I see your boost cut is set for 319 so i would assume that you want your boost to be around 300-310 load. You might want to try BCLO at 140. 140+159=299 load! Try that and let us know how it works out

i really want to get it working man, its perfect for holding boost from what I've seen.

No im not tuning my own car lol its looks interesting though....since im in Gainesville I just play around with the map since I can only go down to Cwills shop so many times a semester...I put in the Tephra V7 myself and its perfect with the big maps and all the other features.
