What size tires?

I had some valve chatter/ping on my stock ford tune on rare occasions and others on here have told me the same thing as some of us have posted a regap on our spark plugs. My truck is a 2012fx2 5.0 with 23K. I just pulled my plugs which were set at .051-.054 and took them down to .045 today. I am currently running a SSI Gen2 87 tune that has been revised and I do not get any noise now, but the new gap has seemed to make the truck more snappy if that makes since. I may have a Ford underlying issue as someone has said and a tune can expose that earlier. I am going to continue to monitor and check my current tune and send in a datalog to make sure everything is good.

Does anyone here do there own tuning? or is anyone using HPTuners? I've used EFI live and HPTuners in the past and noticed HPTuners is available for these trucks.

Badass69 was looking into it last I heard.

I own HP ' s stuff and have the Ford software. I haven't done anything as I usually save tuning for winter when I have less to do.... that said my fx4 now randomly hits the limiter and hangs up in first occasionly so I might dig into it sooner than later. Pretty sure it's my SSI tune.... he even said something about my truck going into limp mode. Well there is an easy fix for that... bye bye sct junk...

So if not sct what else would u recommend?

Lmao, I'm not familiar with using SCT. I came from the evil GM LS engines, still have a few. Don't kill me. I'm curious to see how HP works on these. But to answer the question of the thread, sure it's possible a tune can break parts. Increased line pressure can be rough on a transmission. Keeping it as cool as possible helps. Heat and beating the crap out of your trans will eventually kill it. I increased my line pressure on my GMC and went through several transmissions 17 in two years. The 4000 stall convertor wasn't helping the cause though lol

I'm going to self tune with hp tuners like i have with efi live on my gm trucks. You guys that want to purchase tunes from someone else are going to get SCT.

HP ' s software is similar format to efi live as I own both. The Ford has different tables and mapping than the LS engines I am used to but then I didn't play with an VCT gen 4's either.... just my old gen 3's. I have the Gm software base for hp and made Ford an add on. It's nice as hp can tune a lot more gm pcm's than efi can.

Well that's kind of badass (pun intended)
