ProCharger Stage II Intercooled Tuner Kit with P-1SC-1 - Satin Finish (2006-2013 Corvette C6 Z06 LS7) - 1GP304-SCI
Stage II Intercooled Tuner Power for the C6 Z06 LS7
The ProCharger Stage II Intercooled Tuner Kit is built for 2006-2013 Corvette C6 Z06 LS7 owners who want the proven hardware of ProCharger’s intercooled system while retaining full control over fueling and calibration. This kit is designed for custom combinations where builders may be running race fuel, E85, methanol injection, upgraded heads, camshafts, headers, or other engine modifications.
For part number 1GP304-SCI, ProCharger identifies this as the Stage II Intercooled Tuner Kit with P-1SC-1 for the 2006-2013 C6 Z06 LS7, and the Stage II package uses an additional 6-rib dedicated belt drive. The tuner kit version does not include tuning or fuel components.
True Tuner Kit for Custom-Tuned Builds
This is a tuner kit, which means it includes the core supercharger hardware but leaves the final fueling and calibration strategy up to the builder or tuner. That makes it the right choice for Z06 owners planning a more custom setup than a standard complete system allows. ProCharger’s own LS7 Z06 product information states that tuner kits exclude fuel components and computer tuning solutions, while otherwise matching the complete intercooled system hardware.
- No PCM tuning included
- No handheld programmer included
- No fuel components included
- Ideal for custom dyno tuning and modified engine combinations
Stage II Configuration with Dedicated 6-Rib Drive
The Stage II configuration adds an additional 6-rib dedicated drive compared to the shared-drive HO setup. That added belt control helps improve consistency and makes the system better suited for performance-focused LS7 applications. ProCharger’s application guide lists 1GP304-SCI as the Stage II Intercooled Tuner Kit, 505 configuration, 3""/3.5"" pulley listing, vertical intercooler layout, and additional 6-rib drive.
- Dedicated additional 6-rib belt drive
- Improved belt control compared to shared-drive HO systems
- Better suited for aggressive street and custom performance builds
- Stage II configuration for added boost stability
P-1SC-1 Head Unit - Proven LS7 Performance
At the heart of the system is the P-1SC-1 centrifugal supercharger, a proven ProCharger head unit known for efficient airflow, strong top-end power, and excellent drivability. ProCharger’s published LS7 Z06 system details also note the self-contained oiling system, billet impeller, and billet gearcase construction.
- P-1SC-1 centrifugal supercharger
- Self-contained oiling system - no external oil lines required
- Efficient airflow and strong top-end horsepower
- Excellent foundation for stock or modified LS7 builds
Intercooled Air-to-Air Performance
This kit includes the C6 3-core air-to-air intercooler used on the LS7 Z06 intercooled systems. ProCharger’s LS7 materials describe the C6 front fascia as allowing a single center-mounted air-to-air intercooler system, which helps improve performance consistency and reliability by controlling charge air temperatures.
- C6 3-core air-to-air intercooler
- Center-mounted intercooler layout
- Improved charge air temperature control
- Supports consistent power and durability
Built for Modified LS7 Combinations
This tuner kit is a strong fit for owners planning to move beyond the limits of a canned tune and fixed fuel package. It is especially well-suited for:
- E85, race fuel, or methanol-supported setups
- Headers and full exhaust upgrades
- Camshaft and cylinder head upgrades
- Custom fuel system packages
- Dealer or dyno-tuned LS7 builds

FAQs
What makes 1GP304-SCI different from the complete Stage II system?
The 1GP304-SCI tuner kit uses the same core Stage II intercooled hardware, but it does not include tuning or fuel components, making it the better choice for custom LS7 combinations.
Is this the shared-belt HO kit or the dedicated-drive Stage II kit?
This is the Stage II tuner kit, not the HO tuner kit. ProCharger lists 1GP304-SCI with an additional 6-rib dedicated drive, while the HO tuner kit is 1GP204-SCI with the factory shared 6-rib setup.
