History have shown that its hard to keep those thread free of wars but maybe this time... I would do the exact same work for any JB4 user interested in getting the best out of his tune. And its where pump gas octane is low (California for example with their 91) that this becomes more tricky. Straight quality 94 octane around here allow the use of the stock timing curve and high boost (16+ psi), not that its a no-brainer but almost... Still there is always many tweaks that one can do to improve boost response, traction control...

Green line is Throttle (not DBW, Drive-by-wire throttle) so its was eyim1988 foot easing on the throttle towards the end of the run. Its the actual pedal potentiometer value.

Perhaps traction control intervention? It might also be DME's boost control action (when boost rise up too quickly -> partial throttle closure)...
