6.8 L Tuner for RV?

[LHC30]

I am annoyed by the v-10’s downshift on hills. Started looking for a trans tuner and have almost settled on the 5 Star tune. Price is a little steep but all the reviews and articles say these folks have the tune right. Fuel mileage gain is a side plus, but the trans issue seems most important.
BTW - it’s a 2015 chassis under a 16 Coachmen 21 ft C.
Any input from folks here?

5star is a good choice. If you do some research on irv2.com there was a discount code to save some dollars.

Thanks. Steve got ahold of me earlier and said the same.

never had any issues with this.
shifts are firmer. Slight power increase. It will still downshift often especially with cruise on.
overall I think worth the money.
I have used Brazil’s for my previous 8.1 also. They seem to know their RV stuff.
