What's your EGT getting up to?
I was seeing is spiking past 1350 fast like it was heading outta site and when i was shifting at 3200 it would pretty much level off at 1250-1300. pre turbo pass manifold. i know thats nothing compared to what some peeple see but I like to keep em safe and thats with 28deg and 3200us. and i would imagine some of that could be remidied by adding more then 28 deg at higher rpm because the tune is running a flat 28 deg all the way to 3800
