Hallman PRO-RX-BL Boost Controller, Blue

I have a 20 lb wastegate spring so installing this with the original spring they use and adjusted all the way out still has me at 20 lbs.. not sure if the heavier spring will be enough to adjust up

Even though i have not received this item yet. I have had it on a previous 03 WRX SW and used it for 4 years. It is a great item to go along with a BOV. It takes time to tune it to a good setting (for me 3 full turns from closed). Once it is set, your turbo will start spooling around 2k RPM (stock is 3.5k RPM). I cannot wait to get the item into my 06 WRX SW

Great seller with great product. Will recommend

Anyone who has a turbo should buy this if you want to go Manual Boost Controller route instead of a Electronic Boost Controller.
