Frequently Asked Questions
Do I have to pull the engine to install these parts?
You do not need to remove the engine from the bay. However, you must be comfortable removing the cylinder heads and the front cover to access the camshaft and lifters. This is a significant job that requires advanced mechanical knowledge. If you are not confident with timing chains and valve train geometry, it is safer to hire a professional.
Will this modification void my warranty?
Any major internal engine work will almost certainly void your factory powertrain warranty. Manufacturers are quick to deny claims once they see non-stock components inside the valve train. Only proceed with this upgrade if your warranty has already expired. You are essentially taking full financial responsibility for the health of your engine.
Is a fuel system upgrade necessary?
Most mild cam upgrades work fine with the stock fuel injectors and pump. If you choose a high-performance camshaft that pushes the engine into much higher RPM ranges, you might run out of fuel. Check your duty cycle after the tune is installed. If your injectors are maxed out, a simple upgrade to slightly larger units will keep your engine safe.
What are the main benefits of deleting AFM?
The primary benefit is long-term reliability. The factory AFM lifters are a known weak point that can collapse and damage the camshaft over time. Removing the system also allows you to run a performance camshaft that significantly increases power. It turns your engine into a more consistent and responsive machine.
Can I still pass emissions testing after this?
A mild camshaft will often pass an emissions test if the tune is clean and the catalytic converters remain in place. However, an aggressive race-spec cam will likely cause your vehicle to fail. Ask your tuner about emissions compliance before you select your camshaft. Choosing a grind with a tighter lobe separation angle can help maintain a smoother idle and cleaner exhaust profile.
