Turned it down 2 twists, took it for a spin and it was boosting at 8/9psi, my god it felt like id left th engine at home!!, turned it back up a twist and now its running at 12psi, still feels a hell of alot diffrent to when it was at 16, i didnt think id be able to notice it that much!!


Before anyone asks why id want to turn it down, its because i have recently bought the car, and although it has a folder full of history, there is nothing to say it has been set up correctly etc, so until i get it on the rollers and set up by a pro who confirms it can run higher boost safely, im not taking any chances, call me paranoid ha ha
