Whats the best setting for the tst powermax for common rail cummins diesel?

Question

i have a 05 dodge with a cummins and i bought the tst powermax cr for it and a BD torque converter and i was wondering what the best setting for it was.

and i want to the most power and torque out of it but i certainly do not want to burn up the pistons or destroy the transmission or anything for that matter.

Answer 1

If over 100 hp the trans in time will have issues>Unless you have up grades put in it>I'm running Quadzilla 100 hp mod> always on 100hp> No problems> Check and see if you have a plastic intercooler> If so it will burst around 40 lbs boost>ours 05 did and that's an issue with them> $1200. $ if out of warranty and you haven't mod it>Your truck has 7yrs 70,000 warranty>

Answer 2

Do you have gauges? Specifically boost, EGT (monitoring pre turbo) and a trans temp gauge.

Those will be your guide.

Keep your EGT under 1350 degrees and you should be ok.

If you run really high settings with the TST the injection duration will be so long that a few things will happen. The CP3 pump will not be able to keep up and rail pressure will drop. When the rail pressure drops so does injection pressure. This leads to poor atomization of the fuel and hotter EGT's. This is in addition to the extremely high EGT's that will result from the TST adding more fuel than there is air to burn it with.

To really use the highest settings on the TST, Smarty ect requires compound turbos, dual (or at least high output) CP3 pumps, head studs, injectors... etc!

Further to use higher settings with ANY power adder requires an upgraded fuel system like FASS, Glacier, Raptor and others.The stock fuel system is barely adequate for stock fueling.

Then to handle all that extra power and get it to the ground you have to do more work. For a manual all you really need is the proper clutch.

For an auto its much more expensive. You need a torque converter, full billet internals for the transmission, valve body upgrades, clutch packs and the works.

To try to reliably get much more than 100 or so extra hp out of the engine and to sustain it gets very expensive!
