Here are the dynos from the install of the SMT6 and the a pulley swap.I had the 9lb pulley set from ATI and utilized only one of them.Meaning we used the pulley on the back of the blower only for about a 1/2 lb in boost difference..The first blue line represents the stock ATI pulley combo and no timing control..The second dyno in red you can see we lost a few PEAK hp due to pulling out some timing relative to boost in the upper psi range utilizing a MAP sensor.But look at the GAIN through the rpm range!!at 4000 rpm's we gained 61hp!!!!and an average of 30 hp through the rpm range...Keep in mind this was done with the 1 pulley and with some timing pulled up top to be safe.We experimented with the timing a bit and I hit 425rwhp uncorrected on one run but we decided to pull back the timing just in case and see how the car runs on the street for a while..I am going back in to him soon to get some more tuning as we are still experimenting with the tuning and want to see if a few weeks of running it changes anything on the dyno results.
