The AIRAID system was tested with the stock throttle body. Our system was designed and tested on a stock engine.
Even with the increase in airflow that a larger throttle body will produce, our system will still flow more than enough air. The only problem I can see with the aftermarket larger throttle body is if the outside diameter is larger and then our coupler may not fit, but if it's the inside diameter, then there should not be any fitment issues at all.
Our AIRAID Intake with our 1500 cfm filter will flow about 4x the 6.1L engine requirements, so even if you added cylinder heads, camshaft, larger TB, and full exhaust, our AIRAID system will still flow more than enough air for the 6.1L engine
Any other questions, please let me know.
