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:
