Good 1/4 times For a mhd stage 2 ots

They are, but it doesn't explain the trap.

True, after i realized they have a hard time hooking on a tuned Supra, i just started sliding the car around and doing donuts everywhere for the remainder of the tire life lol

Yea something is off here. I've seen videos of stock tune cars on stock tires cutting high 11's and your car should be making considerably more power than a stock car. My car is MHD tuned on an E40 custom map and I've ran an 11.3 on the street with a 2.04 60' which is utter garbage, I just couldn't get proper traction on the street of course.

I think maybe your tune didn't flash properly or something. Did you do it yourself or have a shop do it for you?

I did it myself, thats what I was thinking too but the app works completely with no problems. I have a set of beadlocks at home I can try but I was scared for my axles so I kept the stock tires on

Try to flash the Stage 2 OTS map again. This will cause no issues what so ever but could potentially help fix an issue. It's been a very long time since I ran just a 93 octane OTS map but I know it was considerably quicker than stock.

Skip the beadlocks for now, you don't need em. You should be in the 11s, even on those tires if they're not thrashed to death.

It is extremely hard to get traction at my local track in general but I was worried it was the tune or something

1.8x 60's is not bad for a stock tire. The issue here is your trap speed is way down for the mods, which directly correlates to power. ET is simply how efficiently you use the available power. MPH is power:weight and not heavily influenced by 60', etc.. unless something else goes really wrong in the pass. Only picking up 20MPH on the big end is a problem. A datalog will tell the story; everything else is just pure speculation. You're either way down on boost, boost is too high so timing is getting pulled back, IATs, heatsoak, etc.. Whatever your issues are will be plainly obvious in the log.

yes

Who should I send my logs to whenever I log a run. I’ve tired contacting tuners but they’re either too far or don’t answer.

Log it and convert the csv. into a file on DataZap, then post the link to your log. It should be like this.

I will do that soon and I will post it

You're only running ~18psi? I'm sorta surprised actually. Timing looks good, you're not pulling. Fuel starved maybe?

It could be because he's on E50. When I was custom tuning on MHD, with Fabian, I was originally going for an E50 tune. Towards the end of our tuning cycle, Fabian told me my car was limited on Rail Pressure at E50, and then told me that if we dropped down to an E40 mixture that he could add a few extra LB's of boost. Looking at all of my logs on E40, my car, under WOT, hits 20LB's of boost at 4500 RPM's and climbs as high as 22LB's of boost at 5,500 RPM and slowly starts to drop off after that. What's odd though, looking back through all of my logs, is that Fabian had me take the car to 6,600 in all of these logs and on the E40 tune the car was hitting 19.9 LB's of Boost (Manifold) and 20.7 Lb's of boost even at 6,600.

So he can see boundaries. You need a little before and after. Fuel pressure makes sense, that's why I asked if fuel starved. I didn't read the log closely.

The turbo will continue to make boost at high rpms, but it's all hot air. That's why it's best to shift the factory turbo at 55-5600 rpms.

Yea gotcha.
