SCT 3015r first thoughts and a few??

Recently installed a 4inch straight pipe and the sct 3015r. My first thought is that I love the increase and power. I recently made the same trip on two separate tunes. It was a 240miles round trip with about 70% highway driving. On the way there I used the street tunes. Truck averaged 15.4 on the dash meter. On the way back I used the performance tune. Got an average of 23.7. I like how the truck performed on the street tune no issues at all. Loved the added performance on the "performance" tune and of course the better fuel mileage but wasn't too happy with the shifting. Felt like it was slipping between 1st and 2nd and 3rd and 4th. Also when I would punch it the downshifts were very rough. I also used the tow tune several times which I am happy with.

My questions??
What trans tune are you guys using with the tow tune? The tuner only has stock, dyno, street, performance, and I think extreme.
Should I still use the tow/haul button still?
The truck is not my daily driver so I am not too concerned about the fuel mileage, but of course Im happy for any improvement over stock. Currently I could not afford a major repair on this truck at this point. Is the performance tune pretty safe to use or should I not press my luck? I am pretty easy on the truck and my main concern with getting the tuner was being able to delete the dpf.

Is that hand calculated?

hey nvr enuff

I didnt think they were seperate tunes. Instead that your engine tune and trans tune were one tune together so that your transmission would shift as aggressive as was required by your engine tune. Yes you can still use your tow haul button but I only use mine when im driving around town or in the moutains hitting alot of steep grades while loaded down. As far as your gas mileage meter it can be thrown off by your tunes so I always rely on hand calulated for the cold hard truth. I would say your performance tune should be pretty safe since there are people running spratan tuners on 210 setting with stock trans and internals and fuel with no issues for 50000+ miles I think your pretty safe. I know I was pretty nervous when I first tuned mine, but last january we hauled about 10k# 2400 miles in a weekend with out the slightest hicup and we only turned the truck off for fill ups and when we stopped to sitdown and eat. If missed anything im sure someone else will chime in.

but hope this helps

When I go to start my tunes it gives me the option to time the engine(stock, tow, street, performance, and extreme) once I select one it the gives me trans options of stock, dyno, street, performance and extreme. It then gives me the option to make more changes to the trans tune but I haven't ventured into that yet. Thanks for the reply
