The big bore kit itself appears to be well made; however, the overall customer experience could be improved. There were no clear installation instructions included, and while someone who is mechanically inclined may be able to infer the correct installation, detailed guidance would be very beneficial. Additionally, there was no recommendation or information provided regarding idle adjustments or tuning considerations after upgrading injectors with this kit. Customer service was also somewhat lacking when it came to addressing questions, and responses could have been more helpful. I hope these areas are improved in the future, as better documentation and support would greatly enhance the product experience.
