It’s not valid unfortunately, the spike near the end means you lost satellite connectivity, usually means you went under an overpass.

So with draggy it can say it is a valid run but the spikes indicates actually it isnt...?? I thought if it passes under a bridge or something it would throw invalid due to low satellite signal. I guess what I am saying is this one of those cases where the run is barely legal?? 🤔

Yeah dragy is really bad with this, they should invalidate it but they don’t. Look at the splits, it took 1.32s to go from 110-120 but then only .83s to go 120-130, obviously that’s impossible. The “real” time of this run is probably around 7.7-7.8.

You're just playing Russian roulette with a 25k motor because you can't monitor AFR, fuel trims, or knock with RaceChip. And without EWG control the higher RaceChip maps under boost heavily causing tuning issues. But hey, you can get a good time out of it a couple times to brag on the internet, right? That's worth at least 25k right there.

Try 1 gallon of E to every 5 gallons of 93. Should be around E20

I wouldn’t guess. You should test the E to determine the ethanol content. That general rule might cause some undesirable results.

I agree completely and test my E content anytime I fill up containers. Where I live I get on average between 81-84%. Please do your due diligence and make sure you E content measure appropriate. With that said, if you have at least 80% E content then 1 gallon of E to 6 gallons of 93 is roughly E20.

Nice, that's pretty good. I typically get 77% at my only station close.

When I lived in Denver, best I could get was like 68%

You can add E85 with any setup, even stock. the DME will auto adjust until it reaches the max fuel trim

if using a piggyback, we recommend the JB4 with E85 because of the following reasons:

1- dataloging to know when you reach max fuel trim before damaging your engine

2- Jb4 has E85 maps; other piggybacks do not. which brings 2 separate issues a) if you use E85 and don't add more boost, you are not getting much of the benefits b) some piggybacks don't even tell you how much boost each map is adding, this coupled with the no data logging is a bad combo
