I ordered the SC 3845, Its Super chips newest programmer, I updated it but have not yet installed it in my truck. I am a bit nervous as it is brand new and just released,I do hope they have all the bugs worked out. The programmer does look and feel well made.

Summit Priced matched amazon, I got it for $306.00

 

I finally got around to downloading a tune in the truck, There was a issue with the programmer at first as there was no Tow Tune, after speaking with SC They got me reprogrammed and on my way.

I installed the 93 Tune and disabled or raised the speed limiter as it is not very clear as to what it does.

The truck seems more responsive and I did pick up about 1.5 MPG. I guess it is ok for the money but I would not say it is night and day difference. I may try to mess with tranny tune a bit and see what that does. I do wish it was a little quicker to do as it takes 20-30 min to change tunes.

 

Hmm did you make sure you had 93 octane already in?


Only reason I ask is because when I installed the 91 performance tune there was no mistaking the power gains, it was a whole new truck and even my friend who used to own it commented about how the truck seemed like an animal and that was without me telling him I had installed the tuner. The first burnout and acceleration attempts I did had me and my dad smiling big time about the gains.


As for the speed limiter setup, I was able to adjust on the old 3815 tuner every mph I wanted to shut it down at up to 140mph, maybe on the new SC FlashPaq they have it where its either on or its off? who knows.


I really wouldn't worry about if the new SC FlashPaq has any bugs worked out because for one, they have a ton of experience tuning these vehicles and for all purposes its probably the same tune a lot of us have been running with minor tweaks for the better for the last few years. I would bet the only real updated thing about it is the kinds of newer vehicles it supports and their quirks.

 

Yeah they had me download a file and it added the features missing, I had about 1/2 to 3/4 tank of 93 in it and the rest was 89. Ill keep 93 in it from now on. Ill give it sometime as I have not really tried it much.

The new programmer just says raise limiter yes or no. I have no idea how much it raises it or if it shuts it off.

I want to try the trans tuning just trying to find a good starting point.

 

That kind of makes me glad to have the older 3815 tuner, you can actually adjust things rather than answer yes or no questions lol
