How do a lot of you get so many miles out of these tires? What PSI are you running loaded and unloaded? I'm running 37 13.50 20s, have 22K miles on them and they need replacing I rotate every 5K with oil change. I like the looks and ride of these tires they just don't last on my truck.

What's the max safe temp? I hit 245 for a minute pulling 15K up 8% grade this weekend.

Got P054E and P0474 at the same time, this might be coincidence but had a bad squealing start on the driver side at exactly the same time as the codes showed up. Sounds like its coming from the wheel or brakes. Cleared the codes and they haven't came back but the squealing is still there...

Like new tuner with EGT probe that's still NIB, has Gerhead and ********** tunes. I don't know if the tunes are truck specific anymore but were wrote for 2015. $875.00

Any difference between them? Power, transmission tuning, etc.?

1150.00 shipped with free license reset from Spartin

Have a like new Ngauge I'm selling and getting a Ndash, trying to get 1200 shipped with a free license reset. Anyone interested?

Any ideas? Got this code today with low oil pressure, engine overtemp, & service advance trac warnings. Goes away sometimes when I turn the aftermarket HIDS on and off but they've been on the truck for 10k miles with no problems.

Can the factory sensor be removed and replaced with this one to read EGTs or do you have to drill and tap the manifold per the instructions? 2015 truck

Been running spar with the egr intact and all 3 plugs unpluged for 3k miles and no codes, lost the EGR last night and now instantly pops up P0113 & P0100 every time I start it. Will Spar revised tunes fix these codes and do I need to plug the lower plug back up?

off my '08 6.4, 250.00 shipped

Will this take the slight wobble out of the steering wheel or is it just for cushioning when hitting hard bumps, etc in the road?

Took my truck to Ford for a squeak I couldn't find. Ended up being my rear 2 piece wheel coming apart. 6 bolts were missing 2 broke off and the rest were finger tight. Nice especially when I was pulling 5th wheels all weekend. My distributor can't find one anywhere or anything on line. It's a 2...

Anyone had one fail yet? Tuned or stock?

I've always heard mine when the key is first on but does anyone hear theirs like this while its running? I don't remember hearing it while running until I put air bags and air horn on it, I know that wouldn't effect the fuel pump just weird that's when I started hearing it.

After a full weekend of driving on Spar tunes, here's my comparison on theirs and Gheads: Spar 600 enhanced to Ghead Race, butt dyno says good bit more power in Spar, TC pulls much harder low end and high end than Ghead. Shifting is crisper and more noticeable on Spar than Ghead, I have traction...

Don't know how much there selling for but I have a Spart tuner in an Edge dash pod and Spart TCM off my 08 6.4 I need to sell.

All new took them off the day I bought the truck: Head lights, tail lights, cab brake light, side mirror marker lights, cab marker light covers. 550.00 shipped for all OBO

How much are they selling for these days? I have a Dashdaq (with Navigation if I can find the card) mounted in an Edge pod, and ******* TCM I need to get rid of.

How many tunes will it hold? Anyway to rename the tunes? I have 2 different company's tunes, if I change both file names to something different they still show as Race and Race, tow and Tow, etc. so don't know which one is who's after there loaded on the TS
