I've never heard of them before personally.
Mine has been hopped up from Bernie since 30k km, I tow and beat the piss out of it every day and now have over 600k km and haven’t had one issue motor wise, 150+ horse tune and tranny tune very quick and cleanHi, Has anyone had any experience with this outfit in Oakville? Ran into a guy in the Beerstore parking lot, he was asking about my L5P, mentioned he had his LMM tuned by them and his mileage improved dramatically. That was 5 years ago with no problems since and he's a landscape contractor/snow plower, so lots of year round abuse. Just curious, their website brpowersource says they've been tuning Duramax engines since 2001, not a lot of hits on a quick Google search.
