You need more width for a better launch, right? If so go with wider tires.
Normally yes, but I think when it comes to price, and worry about them fitting, and the fact that the 285s are slightly shorter, I’d rather have the 285s they are still 11.7” wide

A 295-55 r20 would be 32.8" which is pretty close to your stock diameter of 33", and fill the wheel wells nicely, but it'd be 1.2" wider. I went with the toyo open country at3 in stock size because the contact patch is actually over an inch wider than the stock tires even though they're the same width.

Stock diameter is still like 32 is inches. My tires are not stock diameter, they’re bigger. I also have a 2” leveling spacer that I will remove once I do the new tires. And I’ll also do a 1” lowering shackle on the back so that it sits level. I removed the rear blocks already.

I found Toyo Proxes 305/50/R20 for 168$ per tire on Walmart.com and ordered them.

Also, was chatting with @SrpRacing and he jogged my memory again about the methanol injection. @GearHead_1 you mentioned the oem plugs and indexing, and that also got me thinking, but then I realized that we had some spark blowout on the oem plugs when they were indexed too. But… I had almost no blowout before I started using methanol.

I think I need to swap to the smaller nozzle and see what that does. If we keep getting blowout, I’m ditching the meth kit.

That’s weird, which nozzle you have now ? Keep me posted was going to install methanol also after tutbo upgrade but if thats the case will not bother

I’d have to look, I think it’s the #6 one. There’s two that come in the kit, a 4 and a 6. I put the bigger one on, that’s good for 700hp I think. I am definitely going to swap to the #4 and see what that does.

Traction bars came in. Waiting on tires now, then I’ll make an appointment to get them mounted, I’ll also have them do an alignment since I’m taking off the leveling spacers. Then I’m going to get a 1” drop shackle for the back.

I had to go onto VAS's website as the bag didn't look like it had heim joints in it at first glance lol. But I can clearly see them now.

By the way, I find it pretty interesting, that even though I moved my backup sensors, they still work just fine and the truck does not freak out.

Nice tires ,will probably looking at ordering those traction bars also soon , and did you ever figure out your spark blowout?
Not yet. Ran the tune with no meth today and blew out spark like machine gun fire. Swapping the oem plugs back in this weekend and I’ll see what those do.

Did you swap to the different coils?

No. I wonder if the 95605 plugs sit a tad deeper than the 2021+ plugs and thus can’t get a strong enough spark to the plug… you think?
 
That was what my concern has been. while the threaded end "reach" looks correct the tapered seat sits lower into the head than the flat washered seat. KM

I know, I agree, but I don’t think it sits as deep as you think…. However, even just the slightest of difference could affect things.
 
I think the tapered seat is about 1/8 an inch deep. Honestly I was more concerned with contacting the piston crown, glad that did not happen! One of the ongoing complaints for Ecoboost is poor ignition, now with your experience maybe the 3.5s just have more turbulence in the combustion chamber. That would explain Ford going with indexing plugs.
Any luck finding a colder than stock gasket-ed seat plug? KM
