Should I be concerned??

Ok, yesterday we were on a poker run, beautiful weather, perfect day.
Decided to stretch the 5.0 legs, and do a run in Dragstrip Mode. Left the traction control on since wasn’t looking to melt tires. So, when I launched the car, pulled like crazy through 1st, small tire chirp into 2nd, then it fell flat on its face with barely enough power to move itself. No lights, didn’t recall any Advancetrac warning, just no power. Almost felt like limp mode. But once I hit the gas again, it was back to normal.

Has this happened to anyone before, or could it possibly have been the Advancetrac flipping out about breaking traction when shifting?

It ran absolutely fine the rest of the day.

Car is an A10 2018 with only a Lund 93 tune, JLT, and Roush exhaust.

See if you can reproduce it under the same or similar driving conditions. If so then datalog the tune and send it to Lund. They should be able to diagnose if it is a fuel delivery issue or something else.

Tuning needs tweaking.

or maybe you starting getting wheel spin and the traction control/advance trac did its job

What kind of times & traps were you running?

datalog it duplicating the problem and send it to Lund. Tell them the scenario.

Try it again with advance trac off. Even though the 2nd gear wheel spin was only a chirp, it could have engaged the nanny due to the speed and possible slight rear end wiggle. The CAR'S rear end wiggle....that is....

Datalog and look for knock. The only time my car felt like it fell flat on its face was from timing being pulled due to knock

Definitely no knock. I watch that pretty close with the NGauge. Will have to try to duplicate when the roads are dry.

Haven’t had it at the track, yet. I need to, but never seem to have time.

That’s what I’m kinda thinking. I’ve done sprints in Dragstrip mode before without disabling the nannys, I don’t think it broke traction between shifts, definitely bouncing off redline with the gauges flashing red, but no reduction in power.
I’ve had the tune for over a year with no issues. Car tends to sit for 2-3 weeks at a time, so maybe that had something to do with it.

Definitely gonna try to duplicate with datalog to be safe.

Gotta keep it healthy, going Paxton this November.

My car does the same thing due to the rev limiter.
