My lbz keeps throwing a "boost a perf" code when it is cold. What does this mean and how can I fix it?

If your truck is still stock, it means you need to take it to the dealer A.S.A.P. imho

Which version of Crazy Larry? v2.3.1 has issues. This code is one of them. Down load v2.3.2 CL from website and problems should be fixed. Note after changing to v2.3.2 your peak boost may decrease from 28-30 psi to approx. 25-27 psi. Let us know how things end up. Hope this helps!

Not sure if it matters or not but the light comes on in tow/economy and performance when the truck is cold. I hardly ever use CL. If I run stock mode until the truck is warm I never get a light
