egr valve question

[ols0051]

Thanks for ther great info, I'm going to order a new upper and lower intake in the next few days which one would you choose. I was thinking of the trickflow street for $350? I'm sure it flows much better than stock,but It also is about $100 cheaper than others. And for the extra 100 I don't think the others flow that much better. I'll also go with a 65-70mm tb. The only mods so far are k&n panel filter, timing 14deg,3.73,5spd,subs welded,1 5/8 shortys, mac off road X pipe, Mac cat-back,msd 6al,msd coil,8.5 msd wires. a/c delete,smog pump the trash, weld draglites,26x10.5 et streets. drive shaft loop. best so far 14.40@95 2.1 60ft. Any ideas pass them on. This winter maybe afr165's.
