Gen III 5.3L Peak Speed Shop Radical Ported Intake Dyno Results
Here are dyno results from Peak Speed Shop's Radical porting of a Gen III GM Truck Intake Manifold.
Stock 2001 GMC Sierra 1500, 5.3L. A tune was done prior to the "before" results to factor out the effects of just tuning the stock setup. Dyno was before/after test on ported intake and throttle body only.
7 Gain in Peak RWHP
6.5 Gain in Peak RWTQ
Gains were seen throughout the power curve with points in the curve seeing as high as:
9.5 Gain in RWHP
9.5 Gain in RWTQ
Intake manifold inside before RADICAL porting. Obstructions cause poor airflow to 4 cylinders.
Intake manifold inside after RADICAL porting. Obstructions cause poor airflow to 4 cylinders.
To order, go to TRUCK - Intake Manifold : Peak Speed Shop, Boosting Horsepower...Adding Style! or call us at 719-651-1952.

Here is a photo of the GenIII intake and the GenIV intake:

GenIV
However, you will probably discover that the cost of switching over to the GenIV TBSS intake manifold, fuel rails, etc. would cost nearly as much as simply going to the FAST LSXRT manifold.

I wouldn't bother with intake improvements with a turbo. The turbo does the work, not the intake in that case...so the gains are minimal. My edelbrock pro flow is only on my truck for looks lol. Stock48 runs 9s in his truck with a bone stock gen 3 intake lol. Turbos make airflow issues in the engine go away
