With this turner, can you manually shift all 6 gears? For example, can you hold the tranny in 5th while towing. ( Al, 12/24/2018 )

Unfortunately we do not have a way to manually control all 6 gears. We can promise that it will hang in each gear a lot longer than with stock programming.

1) Does this have an adverse effect on emissions? In other words, are you "Pulling a Volkswagon?"
2) My primary need is fuel efficiency. Don't need more power. Can you taylor a program to conserve fuel by (a) allowing slight slowdown on climbs and (b) allowing slight speedup before engine braking on descents? ( Geoff Wilson, 10/12/2018 )

1.) We have not had any issues with our customers (even CA customers) passing emissions testing. We DO recommend returning the PCM to stock just to be sure as it's a quick, simple process.

2.) We can't guarantee fuel mileage improvement on an RV. We can guarantee much improved shifting performance and power. The things you are asking about would not really be a programming feature, you'd have to still control those things with your right foot ;)

are the improvements noticeable with the stock air intake and a stock headers / exhausted. Will you ship to CA. Do I need to have a mechanic install this program ?

Thank you,
Fred ( Fred, 09/30/2018 )

Fred, the improvements are very noticeable with all the factory components installed. We do recommend the Banks headers to get the most out of the engine, but not needed for a great power gain from just the programming.

Just purchased a 2018 Forest River Sunseeker RV Ford E450 and V10 engine. What performance options are available for this unit. I`ve only driven a few hundred miles and am not impressed by the stock unit. Also are there any monitors available for engine read outs including fuel consumption? ( Jack S Williams ? , 09/13/2018 )

We recommend our UltraPower Custom Tuning

How much on the average will this improve my mileage? ( Steven Andrews , 09/07/2018 )

While we don't guarantee any fuel mileage increase, most of our customers will see a slight improvement. I wouldn't say much more than maybe 1/2 MPG increase.
