I bracket race my '05 3V Auto and was having trouble with a "twitchy" throttle while staging the car as well as when I would drive the car onto the trailer. Lito made me a tune that made the throttle feel more predictable and smooth. I took the car to the track last night. He also dropped the shift points down 500 rpm and it ran a tick quicker than the "canned" tune that came with my X4 I bought from a vendor in the states. The car was super consistent and more enjoyable to race, especially at the starting line while staging. All I had to do was make sure my water temp was the same on each pass and then stab the throttle. I love this 3 valve Very pleased with everything and he was patient with me as this was my first time learning how to data log with the SCT programmer. Thanks Lito !
