My trailer with my motorcycles and gear will be around 3500-4000lbs. I have pulled this configuration before when my X5 was stock to Michigan. Now I run the Stage 2 (91 oct) for my daily drive, I don't ever flog it. I found I get better mpg's and it's overall easier to drive with this tune. (I have stock cats)
I've grown up around diesels all my life and when towing, high EGT's are not your bad. I'm going to buy a 7" fire tablet so I can monitor the egt's and a few other parameters if I choose to use the Stage 1 tune for towing. I've pulled with it stock before and it works good, It's not a speed demon up large hills though and when towing, more or some extra power is always helpful.
Is anyone on here towing and using any of the MHD tunes? From Indiana to Florida I have to go through a couple mountains through Kentucky and Tennessee. (I call them mountains compared to Indiana) I'm worried that prolonged higher boost pressures will increase egt's to an unsafe level. It's a shame we don't have tuners like diesels that monitor egt's automatically and cut boost pressure when a limit is reached. I know diesels are used for towing a lot more so this is a bigger issue with them. I know with gas motors ignition timing along with boost pressure are the contributor to bad things happening to an engine.
I'm looking for thoughts or feedback from actual people towing, or Justin's input. I'm not looking to kill a trans or toast my engine. I'm sure running stock is the most safest options and I'm not past doing that. If I have time and weather permits I'm going to try to do a few Stage 1 trial tows and monitor everything.

the DME's in these cars have similar failsafe's for EGT. that's not just a diesel thing. There are safeties for cat temps and etc.
ALBIET, I personally have not thought about our X-series brethren whom may be using these vehicles to tow. So I openly admit that the OTS maps although not dangerous (due to being moderate) were not catered to the Tow/Hauling.
I tune diesels and gas pick-ups and etc. as well. So I'm familiar with changes that should be made for towing/hauling.
Question......
How many of our X-series owners use their vehicles for hauling/towing? If there is a good amount maybe I can talk to martial about adding a map specific for that. Or you guys can get a custom map for that.
Thank you for bringing this up very very valid concern. I'm so used to everyone having 135,335, 535 and etc. I never pondered our X-series suv owners needs. So I apologize for that.
