The first thing I'd look at is the Wastegate Duty Cycle, Target Load, Boost Desired Load Adder, and Boost Cut Limit tables.

79240

After a bit of fiddling, this is what I'm currently running on my car, but with the mods you have (filter, intercooler, exhaust, fuel pump etc) you certainly don't want to be just blindly copying mine, especially if you don't understand what you're changing is affecting, and why!

This will allow you to modify your boost level and fuel cut limits, and will get you into those higher load areas.

I'm assuming that you've got a wideband O2 sensor available to monitor your fuelling, and you'll be closely monitoring the Knock Count in EvoScan before making any changes!


I would highly recommend checking out some of the threads listed here (https://www.clubvr4.com/forum/showthread.php?77177-Useful-ECU-threads-check-here-first) and get some understanding of what's what :)
