I had my turbo and intercooler professionally installed, the guys that installed did a great job. It took a little longer to install that what was quoted, however. My 2001 Grand Prix GT Coupe has never been quicker. Prior to this, I had installed a K&N filter kit, a Dynomax exhaust and a DHP programmer. Accordingly, the K&N kit and the DHP programmer had to be removed to make way for the Cartunning Turbo and Intercooler and WOW. I had it dynoed before (167khp at the wheels) and then dynoed after it was installed. I gained 132.2 khp at the wheels. This means it goes from cruising speed to 190 km in no time flat - no Turbo lag at all. I am quite impressed with the Turbo.
