    • https://www.amazon.com/gp/aw/d/B07XL7LLVS?psc=1&ref=ppx_pop_mob_b_asin_titlehttps://www.amazon.com/gp/aw/d/B07XL7LLVS?psc=1&ref=ppx_pop_mob_b_asin_titlehttps://www.amazon.com/gp/aw/d/B07XL7LLVS?psc=1&ref=ppx_pop_mob_b_asin_titleTap on a clip to paste it in the text b So, I thought I'd pass this along for those of you who haven't invested large quantities of money into your headlights already.  Keeping in mind that mine are severly faded stock lens's with stock halogen bulbs, I think we all know how pathetic and dangerous that combo is! I started off with machine polishing with meguires #2 mirror glaze fine cut cleaner, about a 10 min.job, then clearcoat with spraymax 2k, (optional), but polish job will be much clearer and last longer. I always have to chuckle when I see people chucking their headlights because they're dull! They'll be better than new when you're done! Next I searched for the best bulb money can buy. I just happened to come across these on amazon, and for the price ($39) and reviews I decided to take a chance, Fahren, 60 watt, 12000 lumens LED's, I know what you're thinking, flickering, scattered light and no high beam, well you'd be wrong, these things are actually pretty dang amazing, they really are 300% better/brighter than stock! Beam is adjustable and has a pretty good cutoff, doesn't blind on coming traffic. And high beam actually kinda works. So far the best lights I've personally ever had, just hoping they last a good while. Maybe not quite as good as some high dollar projector HID setups but again, $39!!! https://www.amazon.com/gp/aw/d/B07XL7LLVS?psc=1&ref=ppx_pop_mob_b_asin_title          
    • You are describing something very similar that happened to me.  It did turn out to be an engine miss under the same driving conditions as you are describing.  Mine started just after I installed RV275 injectors.  I didn't notice it immediately because I wasn't driving anywhere to utilize the power.  It showed up on my first tow (only pulling a 4,000 lb trailer), mostly when accelerating in 6th gear.  It felt like when a gas engine has an irregular ignition miss and, like you say, I couldn't hear it but I could feel it under a load in the higher gears.  For awhile I even thought it could be mechanical.  This haunted me for about 18,000 miles.  I use a Smarty S03 tuner and I even set it back to stock.  The miss disappeared, but so did the engine torque.  To me the test was inconclusive.   I lived with it and tried various things - I even replaced the transmission mount - all to no avail.  Last December I was getting tired of hearing the timing rattle (enhanced by winter blend fuel where I now live) so I set the timing back to stock and left the rest of the tune alone.  Timing rattle gone and no engine miss!  Under any condition!   I left the timing set at stock, even through the summer.  Periodically, I advance the timing just for a test and sure enough the miss returns.  Running stock timing has had no adverse effect on performance or fuel economy.   May not be your issue, but then again...,   - John
    • Have you tried it with out any tuners. Clean battery terminals. Has WT-mod been done?
    • If the master cylinder drained while having the brakes apart, you could just have air in the master cylinder. You may need to bench bleed the MC or if it's level when mounted in the truck, bleed the lines where they attach to the MC and then again at the wheels. 
    • As usual, I took only half of the advice @Me78569 gave me, hopefully this turns out better than my headlight experiment.  I bought @dieselautopower units as recommended, but opted to try the 8x.0085 VCO injectors as they were less money than the 7x.009 units.  https://www.dieselautopower.com/diesel-auto-power-100hp-performance-injectors-7x0-0085-vco-vp7x85vco The sales gentleman at DAP said that more holes leads to more haze than fewer holes; seemed backwards to me (for same horsepower) so went ahead and bought the 8-hole. We shall see!  I forgot to ask about pop pressure.
