No shift under WOT

[KCODE]

Cars ride great during normal driving shifts smooth a firm. Under WOT car builds to 15psi boost but doesn't shift and makes a loud rattling noise. Any suggestions?

That rattling really is not good for your engine. If you don't put some better fuel in or cut that boost back, a head gasket or worse will be another problem for you to solve.

You do need to check your governor for a thrown spring.

Rgr that I've since shut her down till I figure out the problem. I'm also running alky. 93 octane fuel. I'm have a power logger I'll install to get a better picture of what's happening at WOT.QUOTE="TexasT, post: 3409733, member: 7348"]That rattling really is not good for your engine.
