My car is a stage 1 by Karl Norris

It spikes 26-27psi and drops to 23-24psi held up to 7000rpm,it then drops to 15psi.

This has been done by Karl and was proven to be safe during many top speed runs of 150+mph at bruntingthorpe proving ground for a Performance Ford shoot.
The fueling is perfect through the whole range.

It is all in the mapping of the chip,but this is not a run of the mill Chip by anymeans

Car is running the following
