Sir Dieseldude,

Just had my 2002 Revo (195T kms) calibrated at Denso Westgate. Problem is it still emits a lot of black smoke. Although I feel power improved as well as consumption. History of the revo is it overheated. Had it overhauled. Changed pistons, rings, lining, valves. Do you think there was a problem in the calibration that's why there is still a lot of black smoke? I'm planning on sending it back to Denso though. Do I need to ask the mechanic or see that what he is doing is correct?
