I have a Hypertech tuner that is 12 yrs old. The guy I bought the truck from bought the truck in 02 & bought/installed the tune in 03. Is there a better tuner on the market? Do they even make Hypertech's anymore? The truck runs great but with technology these days who wouldn't want More Power!
While i'm on a roll, is a CAI worth it on my truck? It already has an exhaust.
BTW . . This is my first Turbo Diesel.

Thanks for your thoughts.

 

If its not broke don't fix it.

#6637 air filter is going to your recommended filter on this site. I regret getting a oiled filter

 

Funny you should mention that. I just changed the air filter with a paper one.

 

I think with certain tuners, there has been such an advancement in their craft, that if it were me? I'd update. Hydra with Gearhead tunes

 

Custom Tunes link in my signature - I'd start there.

 

Thanks for all the great responses. I have some homework to do now.

 

x2 on Gearhead, after running DP tunes for over a year and then driving a similar rig with Gearhead's 6-pos I switched a few weeks later. Runs substantially cooler on EGT's, shifts smoother, and much nicer throttle and fuel mapping. I highly recommend them.

CAI is kind of pointless with the CAC, as already mentioned the 6637 is a very popular mod that a lot of us run, including myself. Filter is around $30-65 depending where you source it (check out Clay over at RiffRaffDiesel), very simple upgrade and installation.

I didn't see gauges listed in your sig, nor mentioned by you. Give some seriously hard thought to adding these to your must-do list, especially running a tuner. The stock programming doesn't really allow anything to get into the danger zone, and running a tuner you can run into high EGT's very quickly. Gearhead's tuning stops the EGT's at 1250 degrees in all but the high-HP tunes. Keeping an eye on boost, transmission temperature, and fuel pressure is also a fantastic idea. My personal recommendation is boost, EGT, and trans temp however others prefer to run either dual EGT OR fuel pressure instead of boost.

A ScanGauge2 or the TorquePro app with a cheap tablet is also a good, fairly cheap addition. I personally have the SG2 mounted over the rearview mirror with a BlendMount. Either one will allow you to keep an eye on other important areas such as ICP, IPR, EOT, etc. You can also pull manifold pressure (aka boost, which allows you to skip the analog boost gauge), and a large variety of other parameters. Either option plugs into the OBDII port under the dash, so they're very much plug'n'play. You can also read and clear codes with both of them which is quite handy, plus IIRC they'll swap between vehicles if you move on to another rig
