Features:
The GrimmSpeed Boost Control Solenoid is the most complete and easy to use 3-Port Electronic BCS. Unlike your OEM 2-port solenoid, the GrimmSpeed BCS will allow for extremely high resolution boost control at elevated boost pressures, providing your tuner with the hardware needed to safely tune your car with rock solid boost levels. Using our solenoid, you are able to spool your turbo quicker and maintain tight control of boost levels throughout your power curve, allowing you to run the max safe boost at any point in the rev range. In addition, our solenoid features a balanced valve to withstand up to 120psi without a slowing response by even a single millisecond.

This is very easy to install and it will help refine your tune and help boost kick in much more smoothly! Definitely recommended for any tuning. 4 stars as I didn't get and brackets or mounting hardware, but I was able to get around it.
This fit perfectly in the stock location and install was easy
Works great on my 2008 Subaru legacy with a 2011 STI Swap. Only thing was mounting it was difficult so I had to modify the bracket but that's probably due to my swap not the product itself
Part was packed and shipped to me same day. Always happy with IIR. Part works great on my 13 WRX.
Works perfectly well with my legacy 2.5 gt (auto), tune required after install. Shipping was quick by IIR.
So after 10 years of straight abuse my original grimmspeed boost controller died, so with a shout out to josh he had me hooked up within 2 days of talking to him with a great price. Why go back to grimmspeed? 1st I was already tuned on it and 2nd it lasted 10 years in shit weather and 100s of pulls and plenty spirited driving days and the 3rd while trying to diagnose the problem there customer was beyond helpfull and was surprised to hear that someone actually modified a subaru and kept it for 10 years
Looks and feels like a quality piece. Really simple install that takes about 5 minutes! Must have item for any modified Subarus when getting a tune!
My brothers 2006 Legacy GT has it installed and does it job so i bought it for my 14 wrx. Must have for all turbo subarus. Manual boost controls just dont compare
I Have one on my 06 Legacy GT, I Have absolutely no complaints if anything it is a reliability piece that i recommend everyone get, i ordered this part for my brother and his 14 WRX , Grimmspeed has amazing products and this piece appears to be a high quality made product. Importimageracing ships fast and has great prices!
