I almost guarantee his low boost hi egt is the cal. Almost every 870 that I see using the stock turbo does this woth the egr delete. When the tune is done it locks it in non egr mode. If you have a stock one and unplug the egr valve. It will do the same things. Often the tuner will put more fuel to it to try and overcome the lose pf power from the low boost, but it just runs hot then. Theres only a few people ive seen that can actually do the 870 right.could you havr the stock calibration put back in to try and see if it runs better?
