Yeah, unless you plan on using your truck to pull some pretty heavy loads, the turbo itself is going to be a blast and you won't necessarily NEED the IC.. With those non-gated turbos, they may be a bit slower to spool up than those that are wastegated, but hell, they are a HUGE improvement over NA, and you will wear a sh#!eating grin.
The only way you'll have out of control EGT's with a non-gated turbo is if you are pulling heavy or have too much fuel for your needs. The coal you can roll in the low rpm's is astounding. You'll be fine once you get it installed and dial in the fuel, especially if you're just running around with low or empty loads.
