Wow negative nancy ^^^ lol.
What Holley CAN do that GM can't (to my knowledge), outlined on the Holley site:
___________________________________
On-Board Diagnostic LEDS for: ECU Power – Engine Run – Wideband Status – TPS Calibration – Crank Signal – Cam Signal. Allow you to identify any Critical engine issues at a glance
-MAP Sensor vacuum hose adapters (1/8th – ¼ and 3/16ths)
-Genuine Bosch LSU 4.9 Wideband Control
-4 Inputs – 12v, Ground, 5v, and Frequency, for things such as additional pressure sensors, or activation triggers for nitrous activation, or a trans brake (Fuel and Oil Pressure Inputs are pre-terminated)
-4 Outputs – Ground, PWM - , for accessories such as; fans, boost control, nitrous control, IAC Kit, and More
-Boost Control – Boost vs Time, Boost vs Gear, Boost vs RPM, Boost vs Speed, Boost Safeties
-Nitrous Control – Single Channel of Wet or Dry, Progressive or Non-Progressive, Rich/Lean Safeties, and target Closed Loop AFR
-Integrated Datalogging to the 3.5” Handheld SD Card
-Free EFI Tuning Software
Plus my added observations:
-Holley wire wrap is nicer than the Chevrolet Performance convoluted plastic
-Aftermarket standalone TCU's are $500+ anyway
-Free software with base maps included for many combos, and no HP tuners credits to buy
-Not sure what you were comparing on the GM Plug & Play; DBW pedals are cheap, and the GM ones don't have a TCU for $1500.
Compared to the Chevrolet Performance kits this is a pretty nice alternative for someone wanting a little more expansion.
We use the Chevrolet Performance kits quite a lot, i'm not dogging on that with you.
Just providing another perspective for people since you obviously are on the OE-only bandwagon.
