FAST LSXRT Dyno Results on a 5.3L
We did some testing on a 2007 Silverado 5.3L engine. It’s a new body style truck that comes OEM with the 90mm throttle body and what looks exactly like a TBSS intake manifold which we were swapping to a FAST LSXRT truck intake manifold.
The truck tested was 100%stock, and there was no tuning done during testing, the OEM 90mm DBW throttle body was used on the 102mm intake.
The intakes were fairly close below 4500RPM, but after 4500 RPM is where the FAST LSXRT started to take off!!
Here are the power gains.
4500 +3.5rwhp
5000 +17.3rwhp
5500 +20.5rwhp
6000 +19.8rwhp
