Rail Pressure ?

I would like to know if running Smarty 4.06 on SW 1 would be safe for my stock injectors? I dont have a rp gauge so I was hoping I could get some feedback from u guys. With all the injector problems on the 3rd gens I am very paranoid. Thanks

Yes you will be fine. I don't think there will be any kinds of problem. I just keep small micron filter changed regular will help the most.

You can run it on any level and won't endanger your rail pressure. You'd have to be running over 23.5k consistently to cause you a problem. If you definitely don't want to get into the danger zone then stay away from adding a pressure box to your mods and you should be ok without a rail gauge.

4.06 doesnt add pressure above the stock level....so no worries....it's just timing and duration....you have to go to one of the betas (4.2-4.4) or TnT to add pressure...

So 4.06 doesnt add pressure above stock levels on any level. So I can run SW 3 with no worries, is that correct? Its just hard to believe it does add pressure with the smoke it makes.

Only the Beta's (4.2, 4.3, 4.4) and TnT (if you select the option) have pressure....all of the published softwares that you can download from the site do not have pressure....that will change with the forthcomming Revo (which allows it as a selectable option).....you are cleared for takeoff!


IMHO, level 3 is perfect for a completely stock truck....greatly improves drivability and wont hurt a thing. (powerbreaking an auto being the exception...but that's dangerouse stock as well)
