Put the 11 in there, and move it about . 25 of full foward. Running no plate is a baaad bad idea, you can really damage the pump that way.
As for the vice grips, all he did was shut off the wastegate on the turbo, which isnt a bad thing if you have gauges. The no plate situation could mebe cause you to exceed 35-40psi boost and blow the turbo. You can get rid of the vice grips by getting an 1/8" NPT pipe plug (brass preferably) and removing the fitting that comes out of the turbo, and plugging it.
I`d put that 11 in instead of a stock plate, or if you're good with a grinder, grind your own plate profile like I did. Much better than stock, and a helluva lot cheaper. From what Ive read, no plate is actually worse performance than a good plate.
I would also recommend ck'ing the fuel overflow valve on the outlet of the pump and make sure the spring is not smooshed. A new overflow valve can really change the attitude of yer truck. Theres a seller listed somewhere in the forums that will ship it to you for 42$ total. .
ohya, and Welcome to the TDR Bernie!
