I don't really post on forums, never have. I've been a member since I purchased my car in 2014, but I tend to just keep to myself and read what interests me. I genuinely felt like I needed to write this review however. I placed my order with JST around a month ago, which was promptly followed up by a detailed and nice email from Brian, instead of just some auto generated confirmation. Everything was shipped out and arrived extremely quickly, I was honestly a bit surprised. I finally had a chance to install and everything went great. I will say that the intercooler is a snug fit on this car, so having a helping hand is a huge benefit when getting everything lined up and situated. After install was done I started working back and forth with Brian on the 93 tune, getting it dialed in and working absolutely flawlessly. We started on the E30 immediately after and same thing, results were fantastic. On both it is extremely rare that I see a negative correction, and if there is one it is usually very small. The throttle response is wonderful and there is a noticeable difference from the previous setup I had on the car. I had the opportunity to put my car on a dyno in Houston this weekend and managed to put down 292hp on stock turbo with higher than normal charge and intake temps, which is exactly where I wanted the car to be at this point. I absolutely recommend Brian as a tuner, he seriously does good work and he won't stop working until both of you are satisfied with the results. If you're on the fence and debating between who to go with for a tune, don't hesitate to get in touch with him. Same for their intercooler kit! It is a solid, affordable kit and works very well. I think the most I've seen my temperatures rise above ambient is about 12-15 degrees, and that was with me pushing the car as hard as it will go from 2nd through 5th gear. 5 stars without a doubt. I will definitely work with Brian in the future.
