It’s actually roughly the same mph , the first one was coasting through the finish because I let off early, it’s always been around 140trap though. We haven’t added any more power.

Most of the work in the tune has been on dialing in the launch, it’s incredibly consistent now 0-60 in 2.4 or better every time.

Enabled drag mode in xhp, this makes a measurable difference.

Good DA and getting the start point right to optimize the slope is the rest of it.

What tire pressure are you running? I’ve gotten into the 9.8’s but my 60-130 is always high 5’s or 6.0x. Not sure how else I could get the 60-130 lower.

Normal street driving pressures, 32psi or so.

LFG!!!!!!

[christianb5s4]

That's wild.

Went a little faster since it was cooler. Hopefully when we get those 50F winter nights I can go faster 🫡

Sir, I'm not sure you are aware of this. But your car is, in fact, fast.

Lol nah 4’s will be very difficult on stock turbo. You would need a 50mph tailwind lol

Care to share your settings? I recently uninstalled xHP to fix my bricked DME and do some testing. Found out that without xHP installed, my flash tune wouldn’t hit more than 21psi. So we installed xHP again and got boost back. Ran a 7.1 with no custom settings. Then ran a 6.7 with drag mode on. Going to try line pressure bump again along with max torque settings. It drives me honkers that I’m not running a sub 6 like everyone else.
