The owners manual should give the proper recommendation. Me personally, I've always had pretty good luck with Denso, NGK, or even AC Delco brands. Also, you may want to try using the Iridium electrode. Longer life. Sent from my SM-G935V using Tapatalk

Sure have. Works real good. You may be able to see it a bit from the inside, but overall, it should be barely noticeable. Had it done by Safelite. My insurance didn't cover it. Ended up being around $130.00. Sent from my SM-G935V using Tapatalk

You gotta do it! Sent from my XT1254 using Tapatalk

I forgot to mention that it depends on how you want to do the tune. There are a few few ways to get a tune. The cost will depend on the way you choose. All in all it was in the neighborhood of $600.00, but worth every penny. Sent from my XT1254 using Tapatalk

You know I can't say with 100% surety, but I'm going to say there probably is a difference. I say that just because of the different equipment levels and what not. And, yeah, it's a shame you can't make a simple phone call anymore. Sent from my XT1254 using Tapatalk

I've had three of my vehicles with BlackBear tunes. Can't beat it! Sent from my XT1254 using Tapatalk

anumber1 is correct. When I answered earlier I was at work and didn't have access to my shop manuals. Thanks for the assist. Everyone is usually pretty helpful. Sent from my XT1254 using Tapatalk

Wow, you'd think that GM could come up with a better solution. If I had to have this done, and it looked like that, I think I'd have to drive the truck through the showroom window. There's no reason for a modification to look that bad. Sent from my XT1254 using Tapatalk

Well fellas, through all of this discussion, the only thing I can say, is that I'd rather push my Chevy or GMC then drive a Ford! I'm brand loyal, always have been and always will be. I like my GMs! IMO, I just think Fords feel cheap and never have liked the styling. Call me stupid, but I'm not changing! Sent from my XT1254 using Tapatalk

I know a lot of you guys have newer trucks. But, I love my GM's. I had a 2002 Silverado that gave me 350k reliable miles before I bought My 2010 Sierra a couple of years ago. I'm over 100k and loving it. I always add my own personal touches to my trucks, nothing crazy, and keep on truckin'. You definitely can't go wrong with a good Blackbear tune either. Makes a world of difference! Just something else to think about before jumping ship. Sent from my XT1254 using Tapatalk
