Computer programming, programmers and custom tuning

[Dan Cragin]

There are many companies out there advertising custom tuning for the Dodge Viper.
I believe DC Performance can provide you with the best tuning solutions. DC Performance has specialized in tuning the Dodge Viper for numerous years and has tuned almost every combination of performance parts. In the last year, tuning software has been released for the Viper. DC Performance developed this capability years ago and has been through the learning curve new shops are just experiencing.

We offer reprogrammed PCM's, Hand held programmers and custom tuning. All of our programs have been developed in house on our Dynajet 224 dyno or our Dynapack load dynamometer. DC Performance is known for finding tuning solutions when others have given up.

Please feel free to call for your tuning application.

DAn...the email from your website does not work..It times out...

Dan- can we call you with questions about the Mopar Performance Computers?

I've seen example after example of the awesome tuning DC Performance does (getting a Viper to go fast is easy; getting a 5800 lb. silver SRT-10 quad cab to run 10's all day long takes some serious know-how...heh heh).
Just not sure if you touch OEM/Mopar aftermarket computers.

Do you make any tuning software for the Hemi Trucks?

Did my baseline dyno with air/fuel readings today Dan. Spare computer goes out to you tomorrow. Show me your magic!

Did follow-up dyno today. 1998 GTS with bolt-on mods. A/F mixture went from 12:1 to 13:1 (a LOT less black smoke) and timing must be advanced because the car is quieter. I'll post results this weekend but bottom line is going from #5007 Mopar PCM to DC programming got me 10 foot pounds of torque to the wheels between 4,250 -4,500 rpm to the wheels and a corresponding 5 or so horsepower. Probably a gain of half that between 3,000 - 3,250 rpm. Drivability is smoother and it is effected less by intake temps (subsequent runs do not lose as much power as before).

[EDIT] Baseline run is in red and after run is in blue:

Dan, I'm in Vegas, but will be moving to Texas in the very near future. Is there any point in sending you my PCM now or should I just wait until I get to Texas? How much of a difference will altitude play on a tune?
