HIGH EGT's lbz

I'm having trouble trying to get my EGTs under control. They are at 1000 just driving drown the road. When i try to go up hill they are 1400+. I've been working with a tunner and my data logs. My balance rates are within spec. Timming and boost look fine.This all started when I installed a different engine. With some mods.
ANY IDEAS would be great. Im stumped so's my tunner
THANKS Matt

HIGH EGT's lbzhttp://www.mysmiley.net/imgs/smile/sign/sign0085.gif

I'm having a problem with egt's being high. There at 1000 just cruising at 60mph, boost is at 9lb. When I go up a hill they go 1400+. I've done data logs and all looks good even balance rates. Just HIGH egt's
This all started when I installed another engine in my truck. Its got some mods. 42%cp3, 30%injectors,dannsville 68mm stage 2. My tuner and I are stumped.

ANYONE with ideas, or what else should we check

I did try another egt prob and it the same. so prob is good.

9psi cruising is way too much boost unless your dragging a trailer. Vane position sounds to be way too tight.
How about some more info...?
