Performance Gains

Recommended by top tuners.

  • Fuel rail pressure holds steady through peak boost instead of falling off at redline.
  • Consistent power delivery above 5,500 RPM, where the stock pump typically falters.
  • Target boost holds in higher gears, with reliable tuning up to Stage 2+ power levels.
  • No more fuel cut protection events killing power through the upper rev range.
