If you have a 2.4L G6/Malibu/Aura this is the tune you’ve been waiting for! This tune offers 12-15 WHP increase over stock when used with 91 (or higher octane) as well as about 13 lbs/ft of torque to the tires! Couple this with extensive drive ability tuning and you’ve got a fun, economy minded vehicle to drive! Please note this tune is for the STOCK intake only as 2.4L intakes vary widely on this platform as they are engineered for other cars like the cobalt and the MAF skewing can be horrific.
This is a ship in service for your ECM/TCM, we do not supply hardware.
• Proprietary extensive fuel and spark mapping for high octane fuels.
• Removal of the top speed limiter • Nearly eliminating the drop in power felt when Variable Valve Timing Kicks in (check out any stock 2.4L LE5 dyno sheet for more information) • Elimination of the Power Enrichment delay that causes VERY lean A/F ratios under load. • Revised “nanny controls” for hellacious burnouts and power shifts. This will be a must for anyone who wants to race their car! Not only does the LE5 make more power and low end torque but the computer will now actually allow it to hit the ground. • Increased timing in cruise areas for improved fuel economy: end users report a significant increase in fuel economy (2+ MPG); your mileage may vary. • Raised rev limiter to accommodate the engines new power band. There are many more changes but these are the highlights.
