Mack e7 310/330 tune?

[Iron_wolf]

Just purchased my first Mack 1999 ch612. It is tuned 310 and I need the ECM reprogrammed because it is a old roadway truck and is governed at 60. I can find plenty of info on the 330 and above but what can it be tuned with out changing parts? The 355/380 at 1550 lbft sounds a plenty. Any help or advice would be appreciated

I'm told with my 2000 E7 350 the mack dealer can boost computer to 400 hp. Anymore requires injectors and turbo. They can also set your road speed at any speed you want.

What would it take to get to the 350/380? I know the trans is the weak point but would it require parts?

Not sure what your plans are for this truck but at 380 your gonna have to work at it to ever damage the Trans. Depending on where your located I'd call a diesel tune shop to get your options. I've never bought anything from Rochester Diesel but I did talk to them on phone once and found them very helpful.

Here are the spec sheets on the 310/330, 330/350 and the 355/380. If you have a Mack trans your good regardless of HP. Some of the Eaton Fullers with the lower torque rating might be an issue but i doubt it.

In this home-made chart. A 355/380 has alot more torque than a 400. Any thing bigger that a 400 needs turbo and injectors and cam key way changed. This is 1999-2001 ETECH,'s only and not the 2002 and up CCRS engines

I want to run the truck in the foothills. And loaded I would like it to run out with out boggin at all. It has a meritor trans and I figured it our be the limiting factor. It will need a clutch in the future so I can locate a trans and have a swap ready. Thanks for the spec sheet. I  have seen the chart and I think the 355/380 at 1550lb ft will be a plenty.
