Bumbera's Performance did a tremendous job on the 100000 mile checkup on my Chevy Tahoe. Every Thanksgiving we take a trip to the east coast and the engine now allows the vehicle to accelerate without hesitation. I am sure that my gas maileage will improve drastically for the 2500 mile highway trip. If one has a sputtering engine or one that is idling roughly, see Bumbera's. I am happy I did.
