Just go my car back from Macedo Motorsports in Orlando. Picked up 100 rwhp and 100 rwtq, with just a pulley swap and tune. Larry has a load dyno which helps a great deal in advanced and safe tuning and safe AF. This is the way the car should have come from the factory, so far the tires seem to be holding up very well (however it is real hot right now and the cement is probably 110+ F,) 1st gear can get a little tail happy but 2nd and higher are holding pretty well. I have noticed with the pulley that the car immediately goes to 10 lbs and soon as I get into the throttle and then pegs up to 15 lbs quickly.
