Caterpillar Exclusive Exclusively for Cats The Only Tier 3 & 4 Fix

Caterpillar Tier 4 Tuning

Big Rig Power isn’t just the leader in custom tuning for heavy-duty trucks; we’re the only provider of high performance tuning for Caterpillar Tier 4 Final heavy industrial equipment in Western Canada!


Regardless of the line of work you’re in, heavy duty off-road equipment can make you a lot of money. Big Rig Power can fine-tune your engine to deliver maximum performance, power, and fuel efficiency while minimizing downtime. We are now able to offer these tunes online.  All you need is a laptop, an internet connection and Cat ET and we can tune your Cat remotely.   If for some reason an online tune isn’t feasible, you can ship us your ECM from anywhere in North America, and our tuning experts will reprogram and have it returned to you within 5-7 business days.


Each tune is fully custom developed by our in-house engineering team; allowing us to address each vehicle and customer’s individual needs. Every variable is calibrated to Big Rig Power’s exacting standards resulting in gains that stock files just can’t offer. While results may vary from vehicle to vehicle, the result is a heavy duty tune that will turn that sleepy engine into a thoroughbred!


After the custom tune is completed, you can look forward to an end to costly service calls from your dealership. No longer will you need to float your equipment for repairs. The operation of the machine will go from complex to simple; no more regens! Finally, your Cat will be more operator friendly with no fail sensors.
