Programmers/Tuners

There are different types of Programmers/Tuners

Portable/Hand-Held tuners that program the ECM through the OBDII port.
i.e. EFILive & PPE Xcelerator

Vehicle-Mounted tuners that program the ECM through the OBDII port. Most feature a remote display to adjust power levels and gauges.
i.e. Edge Evolution, Evolution CS & CTS

Vehicle-Mounted In-Line tuners that control certain parameters and install between the ECM and engine/FICM?MAF/MAP harness. Most feature a remote display to adjust power levels and gauges. Many believe these do not leave a foot print or are not detectable.
i.e. Edge Juice w/Attitude, Banks & TS MP8.

Thanks to DrHolliday(Chris) for doing some research on this as well.

LLY:
Years offered: 2004.5-2005 / 2006 LLY is basically a de-tuned LBZ

Compression: 17.5:1 / 16.8:1 (2006)
Injection: Bosch High Pressure Common-rail

Engine Changes from previous model:
Garrett Variable Geometry Turbocharger (VGT)

PCV now routed back through Turbo Air Intake (mouthpiece)
Redesigned Valve Covers, eliminating removal to R&R injectors and prevent fuel from pouring into crank-case
Grid Heater removed
High Idle Feature added
Early 2006 LLY model has LBZ updates including Bosch ECM and internals.

Changes to Vehicle from previous model: Higher Hood-line signifying Model Year 2005+

I guess stock is not required as per the PM?!?!

Only difference now is the addition of dual 6" miter cut black stacks with chrome Pete clamps, even with the top of the cab and MBRP diamond plate cover. 5" from turbo back, with custom center split "even flow" Y pipe on 14" bend up pipe for flow.

Also painted the secondary CP3 (metal part) 1000*F gloss black, along with primer pump delete head. All 8 intake ports on the custom PPE race intake are filled now with nitrous inlets, W/M inlets, Hobbs and other ancillaries, loom plugs are in-line again with the delete of Edge box for DSP5 mounted in top console below the lighted E-Locker toggle and next to the PPE rail and 2K* pyro.

All boots are 200psi, triple boost gauges on the A-pillar, the rest is the same from before, barring the ATS Extreme freshin up with 5 Star converter, all T Case upgrades from Fleece and Merchant, yada yada. The rest, I think, is in the sig :D (I'll throw some more pics in below)
