Description
Optimise your vehicle’s performance with a professional Custom Tune or Retune service from T.I. Performance. This product is a software based calibration service designed specifically for standard and mildly modified naturally aspirated (NA) setups, covering everything from stock engines to Stage 2 configurations. Please note that this product is a digital tuning service and does not include a physical J3 Chip.
Custom Tune and J3 Chip Retune Service (Stage 1 & 2 NA)
Whether you are looking to refresh the tune on an existing chip or require a quality base map to begin your own DIY tuning journey, this service provides the perfect foundation. Our base tunes are ideal for enthusiasts using a J3 Programmer Kit or a Full House Kit, allowing you to perform further fine tuning adjustments yourself.
Once you provide your vehicle’s specific details, our team creates a custom calibration tailored to your exact hardware. We can either email the tune file directly to you or load it onto a chip you provide to us. With a turnaround time of just two business days, you can bypass the long wait times often associated with local tuners. Installation remains a simple plug ‘n’ play process that typically takes less than 15 minutes depending on your make, model and specific setup. Contact us for any questions regarding your specific situation and ideal setup.

Frequently Asked Questions
Are there benefits in custom tuning an NA Engine?
While many enthusiasts focus on forced induction, professional tuning of a naturally aspirated (NA) engine offers significant improvements too across performance, driveability and efficiency. By optimising the ignition timing and fuel maps, a custom tune can unlock hidden power and torque that is often restricted by conservative factory settings, improving your throttle response, fuel economy and eliminating any flat spots in the rev range.
Do I need a dyno first before getting a custom tune?
While a dyno is the best way to extract every last kilowatt, it is optional but not strictly necessary for this specific service. Our tunes are built based on our extensive experience, real world data and proven configurations. However, providing a dyno sheet with your AFR data allows us to further refine the calibration for your specific engine, ensuring the software is perfectly matched to your hardware giving you better value for your dollar.
Can I send an existing chip for a retune?
Once your payment clears, we will provide you with the correct return address via email. We recommend utilising a tracked postage service to ensure your hardware arrives safely at our workshop for its software update. Once received, we typically load your new custom calibration and have the chip ready for return post within just two business days.

I have the mechanical aptitude of a toddler so Jason has been very patient and helpful in breathing some life into my old XH Falcon. Kathleen is also so friendly and quick in processing my orders that I have no reason to shop anywhere else. Would highly recommend

Jason, great service as always. Easy, speedy turn around and the new J3 Chip map has made a major difference to the performance of the car.
I would recommend T.I. Performance’s services to anyone looking to enhance the performance of their Falcon.

A must for anyone with serious mods or looking to fine tune with the J3 Programmer. Great starting point to fine tune, as you don’t have to worry about tuning a Blank J3. My car would not run without the custom tune (16inhg idle with cam, stock was 20inhg).
