So I made the 112 mile trek from big bear down to Chula Vista, near the Cali/Mexico border this morning to meet up with Justin at his office for a Black Bear Performance tune!
@BlackBearPerf , , As many have said it’s well worth every dollar! Justin is great to work with! I was about 35 minutes late to my appointment thanks to crappy Cali traffic jams, and he was very patient and made all the timing work, which was awesome! He had a ton of great advice for my truck!
The tune is absolutely awesome! Opened up a lot of available power, especially since my truck runs in high altitudes a lot of the time. Kept tow haul mode the same, since I do tow during the summer. He played with all my shift points and smoothed them out! That’s I think the most fun part! When I want to downshift and get up and go, now I barely have to put my foot into the pedal and that downshift is real quick and smooth! I had a ton of fun with that tonight coming up the mountain! Towards the final uphill stretch I came up behind a ram 2500 and a custom ford 4x4 van, both with turbodiesels, and I pulled past them quite easily, with very steady power!
While doing the tune I brought up the MAF code coming up a couple times. Turns out it was out of spec and he got it pretty close to perfectly in spec, and that was impressive! Gotta pull out my throttle body and clean that up, but other than that my truck is in really good shape he said! So I’m a very happy camper!
BIG BENEFIT SO FAR: my gas mileage is coming up! Effortlessly did 75 on the freeway and my average was showing 17.2! Pretty impressive for a 6000lb landyacht doing 75 on a freeway! Haha.
I’ll get some video clips in daylight tomorrow to show some of the results off. I’m in love with my Denali all over again!
