2003 Chrysler PT Cruiser Turbo MoPower Stage 1 ECU Flash (MTX/ATX)

In 2003, Chrysler added a turbocharged 2.4L engine to the PT Cruiser lineup, transforming it into one of the most exciting retro hatchbacks on the road. MoPower Calibrations now offers a Stage 1 ECU Flash designed specifically for the 2003 PT Cruiser Turbo (manual or automatic). This tune delivers significant gains in horsepower and torque while retaining stock reliability.

Important – ECU Core Requirement

The 2003 PT Cruiser Turbo ECU was a one-year-only unit. To flash our calibration, you must provide a 2004–2005 PT Cruiser Turbo ECU core. Ship us your working ECU, we’ll flash it with the MoPower Stage 1 tune, and return it to you. We do not stock ECU cores.

Stage 1 Features

• Boost increased to 16–18 psi (automatic slightly lower)
• +15–20 HP and +20–30 ft-lbs torque vs stock
• Improved turbo spool and throttle response
• WOT shift boost hold feature (PCM-controlled boost)
• Signature MoPower exhaust decel popping
• Rev limiter raised to 6600 rpm (custom options available)
• No factory speed limiter or torque management
• Modified fuel and spark maps for safe, consistent power
• 92+ octane fuel required

Perfect For

This Stage 1 flash delivers gains similar to our SRT-4 Neon Stage 1 calibration. It’s ideal for cars running factory injectors, turbo, and sensors, while also pairing well with bolt-ons such as intake, exhaust, and catless downpipes.
