Just had mine bored out to 3.0 liters and installed a stage 2 program and new intercooler lines! I blew the doors off of a Ferrari Testarossa had to back down at the bone crunching speed of 175 mph! It was of course under safe conditions i.e. on the track with 3 passengers hangin on for the ride at first they did not believe ! But afterwards they were shocked so was the crowd! I will be selling it soon due to wanting to stay alive much longer!
