My truck has the troyer tuner tuned for it but I forget which tune I loaded like 2 years ago. Can I just connect the tuner and program another tune or do I have to reset it to factory first like the edge units?

Thanks

 

You do not have to re-set it to stock. You can if it makes you feel safer. Justin (VMP) and the guys I have worked with at dynojet have all stated it in conversation and some posts. You will be fine.

 

Thanks I just wanted to double check before messing up my truck.

 

No worries, nothing wrong with making sure. You always can just to put yourself at ease. It only takes a minute.

 

I just used the performance tune for the first time in 2 years and all I can say is WOW it wakes my supercharger up!
