Black Bear Tune is a most!

[DavidBarlow]

Just returned from Atlanta, GA after getting a BB tune-up from Justin. I got 18.75mpg from Jackson, MS to Atlanta. After tune-up, Atlanta to Jackson=21.25. Very impressive for a 2003 Tahoe 5.3L with Gibson Dual Sport Exhaust System, AEM CAI, Granatelli MPG wires, E3 plugs. Also, Michelin LTX tires and I have been using Castrol Syntec for years. I cannot recommend Justin any more highly than this: He is a man of integrity. If you have an opportunity to have Justin tune you GM vehicle, make the effort. You'll be glad you did. I drove 932 miles round trip to get the tune. Well worth my time and expense. Thanks again Justin. It was my pleasure to meet you.

Welcome to the forum, David. And congrats on getting your tune from Justin. He and Jenna are top notch, and their customer service and support here on the forum are unsurpassed. Glad you are happy with their work, many of us here feel the exact same way.

Again, welcome!

word to that!! Glad you had a nice visit and a great tune.

The Gibson exhaust system has a soft rumble and now that it has the BB tune the sound has mellowed somewhat. Definitely a smoother, softer rumble. I thoroughly like it. This forum is awesome. I have been reading y'alls posts for several weeks now and have learned a bunch. After I bought the Granatelli MAF, I read the post by Jenna. Wasted money; but Justin corrected everything. DON'T BUY A MAF, PERIOD!

 

[COTahoeLS]

So did you or did you not leave the MAF in?

[DavidBarlow]

Granatelli MAF left in. Justin reset the thing so it now works properly. Not knowing about this performance stuff I rely on the sales people to be truthful. In regards to a MAF, Justin speaks to the technology about them and told me they pretty much never need to be changed out. Disregard the hype the sales people tell you. I believe Justin. He reset it to factory specs, I think?

what's a MAF ?

 

[COTahoeLS]

what's a MAF ?

Mass Air Flow (meter)

 

[T3rry]

it's a sensor that's in your air tube between the air box and the engine, looks like a big 4" tube with a screen in it and wires coming off it, right near the air box, it tells the motor how much air it should be expecting.
