I plan to run KFLDHBN as a sole load limiter map in my tune, this is with tial 770s, 4bar map and 5120 hack naturally. This way I should always run at the psi I want, instead at what car wants.
Would it not be easier just to max kfldbhn and ldrxn and tune boost via kfldrl ? ECU might not be actually controlling boost but a bit of work and tunning of klfdrl can't be any harder than setting up kfldbhn. You can set exactly the boost you want when you want.
