No seepage or leaks that I could identify. I'm guessing they drained, & filled but did not refill after cycling gears/getting fluid to operating temp.

Been lazy and haven't gotten around to this, but knocked it out this weekend. 4L came out, 5.5L went in.... We shall see if this fixes things next track day...

I run the exact same. Felt much better on the big turns like turn 2 at Barber & 9 at NSS. Front I could go with Full stiff or Middle. Rear's I haven't liked anything but softest so far especially if it's any high speed track. I also have the Eibach springs too.

It was off in the sense of Map 0. I think I'm going to do the trans drain/fill & pull JB4 off for the next track day and see how that works. Only mods were JB4 & Downpipe.

It's seemed to be indifferent to fuel level but I'm not an expert for sure. Happened on the warm up session with a full tank all the way down to quarter/third tank before I fill up. Unless folks are seeing fuel starvation with a full tank under heavy cornering? **Just reread some past...

Happy Monday Y'all, Has anyone run into this issue when out on the track? Last two track weekends this has plagued my 2020 3.0 auto where coming into hard braking for a hairpin corner the car will not downshift & even goes into limp mode. Throw in some elevation changes or geometry changes...

Ahh pretty much the same news on my end... Everyone swooping up those rears!

Order 2F & 2R with TPMS as well! Thanks for the tip! And yes, got the invoice as soon as I hit buy!

Do you have the optional EWG connection? This sounds very similar to my experience when I first got the JB4 & ran it without the EWG connection. After adding, power delivery was smooth.

Not sure if it's the angle but I just installed Eibach Front & Rear Sways and ProKit Springs and I feel like mine on the ground has much more space than yours from the control arms. Also, if anyone's looking for a thursday afternoon laugh, here's what happens when you install that front sway...

This is what I'm doing for Map 3 so I think you should be fine. I use booster to push 93 octane up to 97-98~ octane and the car's been running fine now that I have EWG harness. I've only had over boosting when running 98 octane on map 3 & catless DP. I sent logs to Terry and he recommended...

Yes, it plugs in between the ECU and engine sensors so it should work. It doesn't have the sophistication/customization of a flash tune, but in my case was perfect for a quick power bump until I decide to get more serious and have one of the tuners on here custom tune the car. Check out the...

7 Months/3,616 Miles Followed Break-in Procedure Up to ~2k Miles Last 1.6K miles was a mix of spirited back-road driving & a couple lead footed highway trips in the TN mountains.

Threading the OBD cable through the firewall was only on initial install. I just unplug the OBD cable and stuff it in the back with the other electrical wires. And then unplug & remove the JB4 from the engine bay. Been to the dealer 3 times (free oil changes & recall) and haven't had an...
