Update: 1/4 mile in 11.19 seconds. Video below

The car is just a totally different beast now. I can't believe the difference. It's my first turbo car so I've never seen a tune make such a boost in power like this.

The bad:
Launch control is useless now. The tires want to break so the power gets cut off immediately and it's just... bad.

The fix:
Disable traction completely by holding down the button for 3-5 seconds, and just brake torque launch it the old school way. World of a difference.

I had the chance to do a couple of runs from a dig against a Dinan tuned M550. I couldn't get a good launch but once we got going, the power difference was nuts. Every time I used launch control it was just lag and the Dinan car would get the jump on me. I'm going to reach out to the Dinan owner again to see if we can do a few more runs, but this time without me using launch control.

RK Tunes has done it again...

Well i can see the addiction of power but if you can't put on the road, then I personally wouldn't do it

And what gives you the idea you can't put the power down on the road? Watch the video again... 🤨

Correct. I'm not sure about the dyno to be honest I'll have to ask Jordan.

That's amazing, I'll be doing a write up on the DME tune but it's probably around the same ballpark. Also curious to know what boost level it's running. Can you do some dragy testing with it, 1/4, 60-130mph etc

Salty, bumpy, curvy road, window down for half the run, and I let off just before it hit the quarter mile. I promise this car will hit 0-60 in under 3 seconds and the 1/4 mile in the 10s. Wait for it.

how are these numbers compared to your DME tune? both tuners are near me so getting some info from people with both tunes would provide some great help into deciding which tuner to go to.

DME tune is pretty strong, i'm using a stack with jb4. I read the OP's post again and turns out i'm having the same issue, car has so much lag when launching with LC. I did 1/8th in 7.36 @ 98.9 (0-60 in 3.4) with a pretty much empty tank.

Very Nice!!

When pushing the car near its limit, i always recommend checking datalogs to make sure car is handling the extra pressure well
