I run the stage 4 map in mine with a gallon of 104 mixed in. the clutching is the trick though. if you need a stage 4 map let me know.
stage 3 won't be enough fuel. it will also detonate with out the race fuel.
i'm the same size as you, and ride with klim tog bibs and tomahawk jacket I wear a fleece pants and shirt, I was getting a little to warm last year so I am switching to a vented jersey this year ,believe me I feel your pain.
I've done rkt drop in kits on my 2 11's and my 13. they all run much smoother and the hp gains are no joke,dan may have a good product but it is pricey considering how long the average guy keeps a sled before upgrading.
I've been running a rkt drop in kit with a slp pipe and controller this combo works very well on my 2013 pro. it does require a stage IV map and 20% race gas .some clutching but pulls really hard. I have not ran a stage III. hope this helps
