Fast printing and PETG. Need help with zits/gaps

Just changed over from Slic3r hoping S3D would allow me to clean up my prints as I print fast after I exhausted lin advance... I have no problems with PLA at these speeds, yes I am aware I can "turn it down" but that doesn't interest me.

Here is my latest benchy.

Marlin config
2500 X Accel/ 30 X Jerk
1100 Y Accel/ 6 Y Jerk (had to turn this down from slic3r where i was at 10 jerk and 1350 accel, any higher I get layer shift with S3D)
8 Extruder Jerk

Printer Info;
Wanhao I3 Base
E3D V6 + Bowden Titan
217 Gram X carriage (Including bearings/blocks/fans/hotend/tensioner/all of it)
300x200 Print bed
Bracing
MKS Gen L
TMC2130 X/Y
A4988 E/Z

I appreciate any input, would love to hear from other people who also like to print fast.

Can't see any of your images. The first thing is that PETG simply doesn't like to be printed too fast. I generally never go over 40mm/s.

+1 If you want PETG to be clean, slow down. Especially xy travel speed (speed tab of S3D)
