Default WTF runs were 15 minutes apart???

See 2 runs attached, 50 hp loss only difference I see is wastegate % is much lower on run10. run8 is 278hp vdyno, run10 is 223hp vdyno. What am I missing? Runs were on same road 15 minutes apart. air temps arent that far off, certainly not to explain a 50hp loss. 3rd gear pulls.

My guess would be that you start out with 20 deg higher BATs. Looks like something pulled a little throttle, some limit you hit or you soft pedaled it. At the end something pulled WGDC, I was expecting to see KR, but didn't. It may just be how your WGDC error correction handles your boost as you peak towards your targets vs. how they work as you drop as rpms rise

I think you really just need to spray some Meth and take the BATs out of the equation :-)

Did it feel like it was 50hp less? Vdyno isn't always the most accurate.

Do a couple 4th gear pulls and see if you get the same.
