Flashpaq 3845

Found a used flashpaq 3845 for $150. Is that a pretty good deal and will it work well with my 03 ? Truck has cai, shorty headers and flowmaster. I read somewhere the flashpaq works best with stock vehicles and may not work well with headers , cai etc...

If it's unmarried, then yes that is a good deal and will work well with your 03, just there will be certain features you won't be able to use because it's an 03 (trans tuning, etc). It'll be fine with CAI, headers, it will even run an 03 with a comp 260. It's more involved mods that you would need custom tuning for.

I'm not familiar with the SC 3845. Are you sure it will support the 03 hemi? The favorite tuner for the 03 is SC 3815. Unlocked they can be found in the $140 range.

Yeah picked it up this evening for $150. Programmed with no problems of course I can't do the trans settings. Hooked it up to internet and downloaded updates and will reprogram tomorrow

Our old trucks are nolonger getting updates specifically for them. If you tuner loads and works that's all you can expect. Any updates for the tuner is to support newer models and may well be at the expense of supporting our early trucks. My recommendation is don't update your functioning tuner. I speak from experience as I had a SC3865 that loaded fine on my 03. I updated it and it would nolonger load. Sayin g I needed to update the pcm to a newer version. (BS!)
