ECM Computer Upgrade - HEATH or SS DIESEL

[Jochen Woern]

Thinking about upgrading the ECM on my 1996 6.5l Suburban.

However, I am not sure which would be the better option for me:

- The SS DIESEL SUPPLY ssd-404:
"Performance Upgraded ECM's (computer) for all 6.5 Turbo Diesels 1996-2005 model years. This ECM performs better then any competitors ECM. Specific to your application, will adjust fuel rate, injection timing, boost pressure, tranny pressure and shift points for maximum power and performance. Whether towing a heavy trailer, or just for blowing off Fords, this ECM will add raw power.

2 versions available at the same price. 40HP 80ft/lbs of torque, or 80HP 160 ft/lbs of torque. Even better results are seen with the addition of a #9 Performance Resistor.

The 80HP version requires a modified exhaust such as our 4" system, and full gauges, EGT and boost."

- The HEATH DIESEL HDP1448 (Which includes the Turbo Master Boost Control):
"Your 6.5 is a great engine design, that in factory tune, is far from being optimized. The Max-E-Tork PCM, Turbo-Master boost control and PMD Isolator are designed to work together to transform your 6.5 into a very respectable performer with strong towing power. Improved combustion efficiency results in increased fuel economy, too. Adds 65 hp and 130 lbft torque at the flywheel."

I am currently running with a Performance Air Intake Kit, the 4" inch Exhaust System from Jerry Jardine, Pinnacle Power Exhaust is in the garage waiting to be installed and I will also get the Gauges for EGT and Boost mounted.

- Looking for the following input please:

1.) What do I use? SS DIESEL or HEATH?
2.) Are there other ones out there which might be better?
3.) Do I really need a Transmission Temperature Gauge as well?

Thanks in advance.
