More FAQs

Does the reservoir have to be the highest point in the system to get all the air out?

No. In theory this makes sense but in practice, other elements are in play that override the theory. This system works exceptionally well as-designed and as- implemented (based upon three years of daily driving and race experience, and upon 10+ customers using this kit for daily driving and racing for up to 2 years).

Will this kit invalidate my car’s warranty?

No.

Does this kit require a tune/Is this kit compatible with a tune?

This kit does not require a custom tune; it is compatible with all OEM and custom tunes.

Do you have these kits in stock (what about the national backorder on GM parts)?

Yes, we have multiple completed kits in stock/ready to ship and have parts for over 150 additional kits. The current/ongoing GM National parts backorder does not affect us.

Will you sell me a stock GM reservoir for my DIY Intercooler tank system (they are on national backorder from GM)?

Yes, for $259 USD + shipping and tax.

Are you the same Caddy Issues that makes upgrade turbochargers?

Yes. Our turbochargers are the dominant Upgrade Turbos for ATS-Vs and CTS- Vsports, and have been since 2020. They will be available on this website soon!

Do you have a kit for CT4-V Blackwings or XTS's?

Not yet but if you’re near Houston, TX, we’d gladly work with you to develop a fitment for either car (or any other LF4/LF3 vehicle). It usually takes less than a day to revise, implement, test, and validate a new fitment.
