Irate Diesel Boost Fooler - 1994-2003 Ford F-Series

Irate Diesel Boost Fooler – 7.3 Powerstroke (1994–2003)

If you’re pushing your 7.3 Powerstroke harder than stock, the Irate Diesel Boost Fooler is a must-have upgrade to keep your truck running strong under higher boost levels.

Why You Need It

1994–1997 (OBS 7.3): Once you climb past 35 PSI, the factory MAP sensor begins cutting in and out. This causes power loss, inconsistent boost readings, and overall poor performance. The Boost Fooler corrects this issue by keeping the MAP sensor stable—even when you lean on the turbo.

1999–2003 (Super Duty 7.3): Many tuning options (especially anything other than Gearhead) can trigger overboost codes when the truck starts building serious boost. The Boost Fooler prevents the PCM from throwing codes, keeping your engine pulling hard and clean.

Key Features

• Pre-set and ready to use — no adjustments or tuning needed
• Plug-and-play design for a quick and simple installation
• Prevents overboost codes on tuned 1999–2003 trucks
• Stops MAP sensor dropout on 1994–1997 trucks over 35 PSI
• Improves performance consistency under heavy throttle and higher boost

Just plug it in, hit the throttle, and enjoy boost the way your 7.3 was meant to run.
