Got some time in at a local abandoned airport strip (1.8 miles) to test the diffrence between a gt with jlt/sct tuned by brenspeed against my stock gt. From 80-140 he was able to pull a car ahead by 110 and kept pulling with just the 87 tune! I'm definitely getting one of these! From 0-105 he had about a car or car 1/2. I'm on stock rubber n he's on 20's. Next test 91 race tune! (No 93octane around here)
