Engine is totally stock. I have ARP head studs but I was planning on waiting until I blew the HG to put them in along with a new fel-pro gasket. I don't think it's the head gasket, the engine ran fine for the 5 or so months that I ran this tune minus the turbo. I'm getting a new TPS tomorrow, I'll see if that fixes the problem.

I'm about to order an egr block off plate, right now I just have the egr tube ghetto capped with some heater hose, a bolt, and 2 hose clamps. I don't think anything is getting past it, but I'm going to totally block off the egr for good measure.

Also, the bogging issue really only happens after 1st gear. 2nd gear I can kinda feel it, 3rd is pretty bad. It's like the taller the gearing the longer I'm in the trouble range so the more I feel it. It's weird, I'm about to replace all my vacuum lines and see what that does.

Thanks for the reply.
