Spartan tuner

[ffbowhunter]

Who here has the spartan tuner?  I am running the 275 tune on my 6.4 f350.  Obviously off road only vehicle .  Has anyone towed a trailer with the 275 tune.  The trailer is around 4k dry.

No I dont have Ford anymore, Cummins now.  But dont tow with hot tunes.  Many reasons 2 being your trans cant handle it and also your egts will go thru roof.  Assume you have guages.  Engine timing is advanced on hotter tunes.  4k isnt much but under load like hills you would have to back off.  Likely on hot your egts spike to unsafe level just playing around.

Thanks mud I will drop it down the the 210 tow tune.

Thanks mud I will drop it down the the 210 tow tune.

I would think thats still too high for towing! Definetely keep an eye on EGTs
