Sorry for the lack of response regards to dangermans GT3071R but i havent been able to drive it much due to the lack of a license. Had some friends tune it on the road with me in the passenger seat and we are certainly seeing some big gains over the 2535. Dialing in over 20psi gives it some big mumbo, squeeling the RA1's coming onto boost in 2nd gear. At 16psi power feels linear, definately doesnt give you the excitement of 20psi+. What i havent ironed out is the boost drop with a suitable controller. Im getting a jaycar IEBC soon after my PFC somehow doesnt want to control boost and the manual turbotech's arent upto scratch with too much boost creep. So i have been relying on using the adjustable actuator.
