I need some advice. I want to see what others thoughts are on this. This week I am probably going to order the TRS package for my 2015 GMC SLT. It would me the Morimoto HIDs (35 watt 4500k) with the XB LED fog light replacements. But before I do, what are your thoughts on the XBs being to bright? I like to run my fog lights during the morning and late evenings but want it to look good not to bright. Should I just order the VLEDs for fogs and Morimoto HIDs for the headlights or order the whole package, being the TRS setup.

any ideas? Should I not replace the turn signals or brake light with leds

Alright guys. I am ticked and need some help. I replaced my back up lights (all of them) with 921 LEDs. They weren't cheap. $20 a pair. I ordered 6 more to replace the brake lights and blinker lights. I did not realize that a 921 and a 921 LL was different. Is this right. At the beginning of this thread says GMC 921LL are turn signals and brakes. I guess my question is, is there a difference between these 2 or did I order the wrong bulb

I know people will ball BS but I was getting 18-21 mpg stock with just a level. Now I have 22" wheels and 35" Toyo MTs. Of course it went down tremidously-12-13MPG. I have t had it done long but the last fill up with 91 and tuned with my Diablo I was at 19 mpg.

Yeah. What Doug said? I wonder if they make it in a 35" 22

Factory GMC 22s with 35" Open Country MTs. I lucked up and found the 22s from a friend.

thanks man. Thinking of puttin round chrome nerf bars. Got lights coming from TRS. Cold air intake and exhaust. And I'll be kind of done

I have scanned through 114 pages of exhaust on here and got overwhelmed with all the different configurations and information. Can some one, that is happy with their set up help me out? I want to go with duals out the back, no drone, medium/deep rumble but not super loud. Just want her to sound good.

PM sent Kerrslight....got a ? not about tuning

Thanks man. It came in today I will start learning how to use it tonight. On the 91/e85 tune what results did you see? is the "91/e85" referring to gas? Do you mess with turning off anything or any kind of shift points etc? I doubt I mess with any of these things but I am really trying to understand what the hype is about and how to benefit best from the device outside the reason I mainly bought it was to cal my speedo after I put a lift with bigger tires.

I have a t1000 diablo on the way. What do you guys think the best set up would be until I get it costumed tuned? I been looking around but am a little confused from reading all the info out there.

Are the 2014 and 2015 Sierra 1500 using the same bulds? I looked at the chart above at the beam High/Low Beams - HIR-2 (9012 LL) but most web sites do not list this part and I do not see a cross reference. What am i missing?
