I was on the Uprev web site reading up on this product and just seeing the advantages on it. Its pretty much the only progammer avaiblable for our trucks.

First things first, how do you like it?
Is it worth the $700?
What are the gains you have seen on the track with a custome tune?
When you data log, do you send out the data to Uprev to get a custom map?
When you turn the truck off, does it switch back to the stock map?

Love it! I did mail in tune, and upgraded to Osiris haven't made any changes so far.

Yes, consider I bought the Cipher for 400 and paid 500 for my tune, so I paid 900 and overnight shipping of my ECU to Texas. 700 is a bargain for some of the best/safest/ gains anywhere. It is the only one that helps ensure the safety of your engine!

I'd do it all again, see my sig. Look at my sig, and think about the results I got from the Mods I've done. No headers. Very good results! Just read of a Tuned and S/C 4.6L F150 in Truckin Magazine, that doesn't match my results, and they were comparing it to a Lightning!

Yes, dyno info helpful too.
No, MAP stays until you switch it, no nuisance to using this system on daily basis. "idhitit2:
Didn't think it would be worth doing the mail in tune but your results look promising.I have the 22" magnaflow which muffler do you have?
