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 just over 5k on my truck and I have been to the dealership over and opened a case with GM (that I have not had time to follow through with). I do not have the problem going down hill but I will tell you what I am experiencing. Maybe, its the same thing or at least try it out because if it is and you can replicate the noise if and when you decide to take it to the dealer. WHILE ACCELERATING (Above 25-30 and below 60) in whatever gear the truck is in RIGHT BEFORE it is going to shift I can let completely off the gas and when it downshift it makes a clunking sound. For example, while accelerating (normal acceleration or light acceleration) in town I let off the gas because the car in front of me is slowing down, stopping or whatever and I just have to let off the gas, it clunks downshifting. does not seen to do it in 1st or 2nd.

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.
