got custom tune today from pdi and tryied to install and it says unknown vehicle i've never had the triple dog installed in my truck its brand new.

 

might be missing the last 4 digits of the VIN in the ECM.

 

i tried it on my 06 and it didnt work either the tune might be messed up.

 

x2 the vin you in st george dms?

 

Mine did the same thing. I did an update through their website and then it worked fine.

 

whats x2 the vin mean?

 

lol it mean that person thinks its vin number too.

 

mine did'nt want to install but after downloading updates everything was o.k. by the way had to have the updates e-mailed to me as its hit or miss trying to download from the web site- they're having big time problems since being hacked.
