I see that some people are swapping to a 2bar map sensor with larger injectors and using an SCT tuner when running boost (blower or turbo).

Are you also adding a 1:1 fuel regulator and return line that is manifold referenced?

When tuning the SCT, is there software available so that a person can tune his own truck, or do the tunes have to come from a shop?

IE, you purchase a 1 size fits all "blower" tune via email, or you can tweak your own SCT tune to fit your exact mods?

Is there a 3 bar tune?

When using the SCT, you can get a kit to tune it yourself, but you won't get a 1 size fits all tune with it without some extra coin. The kit to tune it yourself is pretty expensive right now.

No need for a 3-bar unless you are running alot of boost, and if that is the case, you would probably need a whole new fuel system (with return), and would be better off using a stand alone ECM.

Your fuel is all controlled by SCT and input to the MAP.

When you get your SCT, if they are also a tuner, they will provide a tune that is pretty close, at least close enough for you to drive and log some data. Then, based on the data, they can make adjustments to fine tune it.

Chris at PIE did mine and after a few emails, he hit the tune dead on.

Like said above.. you dont get a "1 size fits all blower tune" via email. If you opt for the email tunes (you'll need a datalogger), you give them your mods and they'll send you a tune according to that as a base tune to get you started. Then you do some runs and send them the information from the datalogger via email back to them and they'll tweak it accordingly until you've got yourself a nice tune.

Very true. Given who you had do the "email" tuning for you, certain individuals have done a tremendous amount of tuning for our applications, different motor sizes/mods/boost non boost etc. When you send your mod list, the tuner per say is able to go into his files, and possibly have a tune that is already in action that contains your same mod list.

Some people do run a 1:1 regulator if they have a return fuel system, but it is not required. Our base fuel pressure is higher than other makes, and when you subtract manifold pressure you still have a decent differential to work with.
