3rd time I’ve been back with stalling issues, poor fuel economy and bog down in 1-3 gears. Each time they charge stupid amounts of money. Got it fixed elsewhere in less than an hour. They should not be in business. $1500 for tune and OTR has now cost me $3000! DYNO numbers quoted were overhyped by almost 40kw.

low km engine fitted with their cam package, refused to warranty a failed lifter 1 month after pickup, car kept bucking and stalling until I had it fixed by MPW, avoid at all costs.
