Exactly what I needed
I like it I would buy jt again for my next car. Works great fixed my boosting problem instantly. Will recommend.
Your tuner will love you for providing this. Its a must have
Plug and play what more can you ask for? hardest part was getting the tiny hoses on the waste gate titter. other than that easy peasy. This should help my boost issues the stock one wasn’t cutting it anymore.
Really good product with extremely fast shipping from import image. This boost controller accurately helps tuner gauge accurate boost numbers that your car is putting down versus the OEM boost controller.
My boost was so much smoother and I noticed a noticebale difference in power gains. Highly recommend buying a 3 port.
Necessary for external wastegate
One of the best products you can buy for any Subaru. Came with hoses and everything. And great prompt shipping from IIR.
Had all parts required for install, literally took 10 mins to do, arrived quickly and preferred by my tuner.
Highly recommend this product, Helped keep me from over boosting. Fits perfectly in stock location and comes with everything you need to mount and install it.
