We don't have a dyno in our shop. However, we do report gains based on what customers have reported back. These are better anyhow because they are 3rd party, non-biased, results.
On the radical ported TBSS manifold, customers report about a 10-15 rwhp gain. The 4.8L engines can expect closer to 10 rwhp gain whereas the 6.0L TBSS engines around 15 rwhp gain. Engines that have other mods like cam and head work that demand more airflow can see higher gains.

2007 was a transition year. Later 2007's had the tbss style intake. If your throttle body is attached to the manifold with 4 bolts, it's the tbss style. If it is 2 bolts on the bottom and just one bolt at the center on top, then it is not the TBSS style.

On the stock 6.0L engine, the FAST LSXrt generally gains about 25 rwhp over the stock unported TBSS manifold at a cost of about $1,000. This is $40 per horsepower gained.
The Radical Ported TBSS manifold generally gains about 15 rwhp at a cost of $425. This is $28 per horsepower gained.
So, someone looking for maximum gain should look at the FAST LSXrt. However, for those who are more budget minded, the Radical Ported TBSS gives the biggest bang for the buck.
