I recently bought an arashi adjustable wastegate to put on my stock 06 xt and I was wondering if there's anything special I need to do while installing it as far as set up goes. Car was boosting slightly erratic and had quite a bit of lag. Would build boost and dump it right pretty damn quick. I did recently put in a new BCS which helped a little but it's still not as peppy as it should be.. I don't have a boost gauge so I'm using an obd Bluetooth with the torque app so I know it's not a hundred percent correct. Thanks in advance!
