Hey iv been reading the fourm for 2 years and said time to sign up.
I am about to buy a SCT for my truck for some more power.
My question is how much power can i expect to see and any better MPGs.

Thanks

 

Hope you are going through Hemifever, since he does programming for them and gives you one heck of a discount over the traditional SCT pricing.

It will be almost a night and day difference from stock programming. However, you won't see a whole lot of extra MPGs, mainly because you'll be using the gas pedal more (you'll really like those extra, freed up ponies).

Did you fix your plenum gasket yet?

 

i hope if hes been reading for 2 years he would have known about the PLENUM GASKET FAILURE,

theres only a question about it at least twice a week for the last ?-thing months lol

 

Iv heard of the PLENUM GASKET FAILURE,but never read on it mainly read the custom fab stuff alot on hear. Can you tell me more about the gasket

 

Manifold on these trucks is two-piece. There is a steel plate, with a gasket... on the bottom of the manifold. Gotta pull the intake to fix it. The bolts that hold the plate in place were too long from the factory, so, after a boatload of heating/cooling cycles, the less-than-stellar gasket would fail, introducing a serious vacuum leak into the intake, from the valley of the engine. Excessive oil consumption, fouled plugs, clogged cat, trashed O2 sensors, were the general result. (along with a corresponding loss in fuel economy.)

There are a BUNCH of threads on here dealing with it, including a DIY or two on fixing it.

 

oh ill have Headers before o get the programmer if that will take care of the problem.

 

That will not fix the problem.The plenum is on the intake manifold.
