Yeah already talked with Frank at Vortech. We are the Island distributor of Vortech products. Got the kit for our demo truck before checking if our local tuners using hptuner and efilive could tune a 2011 4.8. Answer was no so just searching out another alternative.

Any chance the new Trinity has a supercharger file out already for the Vortech (Lysholm 2.3) supercharger.

2011 Silverado 4.8 liter

Thanks!
