So my friend has been having issues with his 6AT Pure 600's as soon as he climbs above 6200-6300 RPM. I did notice that his HPFP crashes hardcore but seems to regain somehow. He installed a Helix Overdrive and the HPFP doesn't crash as hard but it still looks messy and causes timing corrections. I added a good bit more fuel scalar just in case, bumped down timing to make it a more conservative tune and reset all adaptations.

He also said he tried another (used) HPFP but the issue was still there. You guys think its still the HPFP? I'm leaning towards yes

Here's a log post helix with the vcv changes aswell. I told him not to go above 6000 RPM until we get this issue sorted. I hate seeing exorbitantly high afr's at high rpm
