I am noticing the boost fluctuating when between 23-27psi and part throttle no load. you can hear the turbo speeding up and slowing down. Also It seems to get to 1450-1500 deg pretty easy, 3/4 throttle accelerating gets to 1400+, smarty set at #4 tnt w/stock timing, my 12v didn't get that hot that easy. What the heck would they hit if I put the smarty on level 10??? Bone stock 98 w/holley blue, 4"exhaust, BHAF, Smarty TNT on #4w/stock timing, waste-gate on. I want to turn it up but cant with these EGT's.
