My neighbor sells racepak. For the IQ3 logger dash, 2 egts probes, tach, fuel, boost, coolant, oil pressure was going to be $2400. But the dash also gives you gps footage, mph and something else i dont remember. Plus you can hook a video camera too it and sync the footage to the logged run so like with thier 3 engine turbin tractor, they were having problems dropping the third motor. In the video you could see the motor give up at like 18 seconds. Scroll to the logger graph and at 18 sec. the fuel pressure dropped so they can help diag problems too. They also include like 4 warning lights, and shift lights. The logger dash itself is $1200 The sensors will kill you. LOL
