First time towing with Gryphon

[champ2675]

Hey Fellas

I'm going to be towing a 6x12 uhaul cargo trailer this weekend from Calgary to Saskatoon about 700km (435 miles) not sure what the final weight will be til I get to the weigh station. I was wondering what would be the best parameters to put on the display and what upper limits to look for. I would assume TFT and TSS/OSS, Load and LPD might be the ones to watch? Hoping some of you more experienced towers out there could help me out.

'06 FX4,the only mods I'm running are a MRBP catback and 285/65/18 BFG All terrain ta.
haven't got custom tunes yet so I'll be using the canned tow tune with 89 octane gas.
the temp up her in Alberta is hovering around -10c (14f) so overheating probably won't be much of an issue.

Thanks
