Records List

At the Cadillac Attack 2023 event in Orlando, Florida, Aric Miller achieved a remarkable 9.8-second quarter-mile at 137 mph, securing first place in the True Street class. His 750whp ATS-V, tuned by Schmidty Tuning, features our +21% camshaft and upgraded XDI Stage 1 Low-Pressure Fuel Pump (LPFP). Unlike rebranded LT4 LPFPs, our LPFP includes the XDI Pressure Limiting Valve (PLV) to safely increase pressure output. We also provide a new gasket and level sensor at no additional cost, offering a cost-effective solution for your ATS-V fueling needs.

Injector Information

XDI-Injectors: $1,999

  • +50% Increased Flow over stock injectors
  • Stock-like Idle Characteristics for smooth performance
  • Precision Matched Sets within a ±0.5% flow variance
  • High Stability at 3,000 PSI, providing perfectly linear performance
  • 100% Drop-In Fitment: No adapters or pigtails required
  • Tuning Modifications Required (fully supported by HP Tuners)

Each XDI injector set is rigorously tested and matched at three key operating points, and includes comprehensive documentation:

  1. Idle Stability: 0.8 ms / 20 bar
  2. Static Flow Reference (qstat): 10 ms / 100 bar
  3. WOT Performance and Stability: 6 ms / 200 bar

This thorough testing ensures reliable, high-performance fueling across a range of conditions.

Camshaft Information

This is a factory GM ACDelco camshaft with a modified Direct Injection (DI) lobe, expertly enhanced by the XDI team to achieve 6.35mm lift compared to the OEM 5.25mm.
This modification maximizes potential within the hardened depth of the OEM camshaft, resulting in a 21% increase in High-Pressure Fuel Pump (HPFP) capacity.

LPFP Information
Our XDI Stage 1 in-tank pump is modified and assembled in the USA, designed to be the only pump on the market with an optimized Pressure Limiting Valve (PLV). This pump sustains full flow up to 80 psi without compromising the PLV’s safety function—an essential feature for high-performance builds.

  • Recommended with the HPFP35 kit (compatible with or without a cam)
  • Proven Performance: Tested up to 625 WHP on full E85, reaching the limits of stock turbos

This pump is a reliable choice for those pushing the boundaries of power while ensuring safety and durability.
