Better torque and drivability!

E30 325e/E28 528e performance chip from Jim Conforti is the ultimate software upgrade with no downsides! Jim Conforti tuned the M20 Eta for more peak power and mid-range torque using premium 91-94 octane fuel. With better fuel and proper tuning more power is available. By making changes in the ignition and fuel maps of the DME we are able to optimize performance with no side effects or compromises. Other changes will make your BMW smoother and more responsive than when it left the factory.

Conforti/Turner Performance Chips have a lifetime warranty and a 30-day satisfaction guarantee. If for any reason you are not fully satisfied with the increase in power and overall drivability you can return the chip for a full refund. Chips are supplied with detailed instructions and are user-installed in about an hour.

Please note: due to global supply chain interruptions, older EPROM chips may be in short supply.
