Might have to switch to DBW but that means i would need a new ECU correct I have one out of my 98ss camaro?

I'm going with dbw with a GM ecu. I like the idea of a simple cruise control set up...

Correct, E67 or E38 ecu plus new harness and 58 tooth reluctor.

As far as easy cruise control, last I checked the verdict is still out on the GMPP E67 ecu's. They are custom calibrations from the factory.

I've done both. After been there done that X4 - I go with the DBW everytime.

Why?

1. you can stuff a lot larger cam in there and with the right tune it won't stall or hunt for idle like the alternative as there is much more control available than just the screw set and idle air motor found in the dbc.

2. CRUISE CONTROL - with a complete DBW, all you have to do is hook any old or new GM column mount cruise switch up and you are good to go. It is that simple.

3. CLEANER - the pedal takes up a little more space, but no cable to run or adjust or look at. You will have wires going to the t/b no matter what - so what is the big deal of adding two more (that is all that is needed to power the motor - all the other sensors/switches are fairly identical in number to the dbc on the i/a and tps sensors).

4. It is THE thing - dbc is so.....10 years ago.

5. Issues have been ironed out - seems like all the aftermarket harness guys have a handle on this now - and there is ample info out there. you can run into some problems as all DBW gm parts are not the same. In other words, a truck throttle body and Corvette are different - so if it is an early DBW, the TAC module has to match the parts being used making mix and match harder. In the current gen of DBW, it is more simple as there is no TAC module, but the t/b and pedal still have to match up. So...a little more homework is needed but once the right stuff is there - you are golden.

So if I have an L92 complete (2007), do I keep the pedal and TB that came with it? I was wondering if that TB will have the performance I am looking for. I need to change the intake to an LS3 style.

Is your L92 out of a Caddi SUV? What intake is on there now?

Yes it is out of an Escalade. It has the truck intake, but I've purchased an LS3 intake. Sorry for any lack of knowledge on this - it's my first time doing it!

Okay...couple more things....

What accessories are you going to run? The Vette accessory and truck accessory are different and interfere with the driver motor for the dbw throttle body.

What transmission are you running...and confirm to me that you have the PCM, pedal, and TB right now off the Escalade.

As a former C5 owner the DBW is responsive but feel is lost. I never was as in touch with my C5 as other cars and arcade games give as much feedback as a C5. The throttle feels soft like a factory 60s power steering setup imo sure you run turn when you want but do you feel connected with the car?

DBW allowing more cam? 5.7 LS1s are running cams in the 240s at .050 and idle just fine, any more cam and it isn't a street car imo and would have a cam far to big for the application.

I do agree the swap has been ironed out and would not have safety concerns.

I want to use Cable when ever possible. I picked up my '01 2500HD truck wanting to go old enough to keep cable and want to keep swaps cable when ever possible. The only drawback to cable is cruise control imo.
