Leaving Home Depot from picking up an extra pressure fitting for my new meth kit, I ran across a 2008 or so yellow charger srt8 super bee... I let it get up next to me and we both hit it running about 55mph... We were dead even until around 85 and I started inching away from him, I let off around 100... Only had him by a few inches but that means the world to some people!!! Lol! can't wait to get this meth running and tuned! I think it's gonna make a big difference out here in this heat! Anyways, thought I would share my latest kill/victim!

Are you running on e85?

Right now I'm running half e85 and half 91. the truck leans out a little if I run straight e85, around 12.3-12.8ish.

Its uncommon for people to run meth and e85 is why I ask. e85 doesnt really care about IAT's as much as gasoline. In other words its uncommon to see both because there wont be nearly as much benefit. Meth is used primarily on this forum as an octane booster.

My tune was done on straight 91, but my truck is flex fuel, so I was just going to play around with the meth to see if I could get the A/F ratio richer on straight e85. Mitch at TES is going to retune my truck on the 18th, on straight 91 plus the meth, and that's what I'll run. It's just getting really hot out here during the day and I can tell a difference in the trucks power, compared to driving at night when it's cooler. I figured the meth will help with that as well. Plus I wanna compare numbers to see what I gain off the meth!

You will see a drop in IAT's with it for sure.

I'm not super familiar with the flex fuel tunes, but I can see it leaning out while running e85 for sure. With e85 you will be looking for the same readout on your wideband gauge, but as you introduce meth you will want it to be slightly fatter. Where it gets confusing is your wideband reads stoich and converts that to the gasoline scale of 14.7:1. Meth likes a lower stoich value under load.

Thanks for the info! I'll post up some results in a few days.... With how much timing, A/F, and HP/TQ.

I with e85 and gasoline mix the general rule of thumb under boost is 11.8ish. As you start spraying meth I would target 11.0ish. Dont be afraid to let it go leaner as revs climb and you approach redline.

Cool! Thanks for the info! I've been messing with it on the street and sure does get rich quick! I ran my truck down to E yesterday and put some 91 in it.... And with the 91 I can't even turn it on.. It makes it too rich! And would bog down when it would start spraying, it would get into the 10's.


I'm thinking about taking another set of plugs with me... Maybe some br6ef? I'm running br7ef at the moment. Would running a br6 help any with the meth, or just stick with the br7?

The meth may allow you to run the hotter plug, but I run 7's with no issues. I'd probably stay there
