This engine remains to be hugely based on a non turbo motor, thus parts are allready on their own Restrict.
A. To start with It can be under no circumstances very good to chiptune engines that utilize a AT gearbox, 2nd of all I don't recomment to chiptune this CFE engine especially! We have operate rather some examination, laman utama and soms assessments with blow off valves not Performing resulting in overpressure through the turbo (which is what they will do) with disastereous consequences!
Chance is that Punch will open a neighborhood manufacturer to recondition gearboxes and market at prices akin to typical AT ones. As you are aware of our gearboxes are examined until 250000km.
