I have been debating about moding my car for 5 months. I have read alot about all the vendors on our board and decided to call James at runnin with the devil to inquire about pulley @ predator ( I had alot of ?). Thank god James has alot of patience as I called him numorous times with many questions about my setup and he took the time on every phone call to explain everything in detail (everytime I called he answered the phone). I knew after 2 days and 8-9 phone calls that James was the guy I wanted tweaking the preadtor tune for my car. I ordered a steeda 2.80 @ steeda 100 idler, gates belt, predator and denso plugs and his prices were less than anyone elses. I just had to post this as you read alot about bad experiences with vendors and not the good ones.
