ISX15 overheating after vgr turbo installed

[tree98]

When you say "VGR" do you mean VGT the proper turbo that the engine came with from the factory?

If it had an aftermarket fixed vane turbo on it when you bought it there's no doubt you have a bad tune and that's likely what's causing your problems. Copy the program out and send it to Rawze for review.

How high is your boost getting? Over boosting can cause severe damage, what engine is this CM870,871,2250,2350,2450?
