i think i've lost a full second in the quarter mile in the last month,at least thats what it feels like. Anyone have any suggestions as to what it MIGHT be? I run at a temp. of 210 F, and i recently blew one of my EGR hoses off,any help would be great. Thanks
P.S. I have replaced the EGR hose

i find it really slow to build up rpm's after 4000rpm.
