Got my hamilton cam installed

Back to the thread! I just installed my cam Hamilton Big Stik that i got from FTE. I noticed a smoother idle right away. When i did the round the block test drive i noticed my egt s where holding around 700 Today i drove it about 200 miles and my egt s are out of control high. I can hit 1350 on a on ramp. The needle moves as fast as my rpm s do. 80 mph 7lbs boost 2150rpm i see 800 degrees. If i slightly accelerate it will hit 1200. I read everywhere they should drop. My boost is lower. Anyways with no smarty i see about 100 degrees difference lower. I always run my smarty on 5 and have never had a EGT issue. Stg3 cp3, 62/71/14,90hp stix,springs, and a huge HTT Intercooler. Really lookin for some ideas to help bring em down. Could I have been sold the wrong cam? I got no papers on the grind as far as any durations.
 
Is power up or down? What injectors, turbo , head work, intercooler , and what smarty programming are you running?
First, check for the easy things. Boost leaks, valve lash, too much fuel for your setup etc....

These cams really move a lot more air than the factory cam will allow. On trucks with closely matched injectors, programming and turbos, you will see major improvements in driveability, power and egt reductions. However on some heavily fueled trucks I have seen major increases in EGT. Before you second guess your decision to buy one of my cams hear me out.

In a truck that is slightly overfueled, the added fuel will help clean up the excess fuel and lower the egts as well as make a few more ponies.

On a heavily overfueled truck there are a few things to consider. First after you have enough fuel to make heavy black smoke, you are effectively using all of the oxygen in the cylinder so any extra fuel you add has no oxygen to combust. What you see in this instance is that the extra fuel turns from droplets to a vapor. Anytime a liquid turns form a liquid state to a vapor it absorbs a lot of heat. It is almost acting like water injection to some extent. A lot of pullers and drag cars use this super rich state to keep their pistons alive.
Now introduce 20% more oxygen to the equation. That fuel that was busy absorbing heat is now producing LARGE amounts of heat thanks to the added combustion.

In short if your power is down and temps are up, something is wrong. Look at cam timing, boost leaks, and valve lash.
If your power is up and temps are up then Congratulations on the added combustion! You were and are heavily over fueled. Get some larger chargers and some head work!

Power is up, yes. I sent you a pm Zach. Only running 90 II stix, STG3 Floor It. 62/14/71 HTT, HTT intercooler, CFM+, Airdog 150, dual feed, Floor It 's best springs. With no box it is slightly lower, Smarty Beta SW#5,7,and 9 all are the same. Beta on the evens with MP8 is about the same. I can't run the Revo TNT cause of the popping.
 
If you can still smoke like a train I believe you have a basic overfueled condition. You need to check for boost leaks at at least 25-30psi. You will not find them all at 5-10 psi.
