OK everyone pulling my fiver up long grade today truck running 50mph boost at 15; egt 1050; oil temp 170. Service engine light came on about the crest of the hill and went off as soon as I got off of it. Afterwards truck seemed to run ok , but I did notice I could here the turbo whistle more. I know my boots are shot 3 out of 6 are fully coated in oil/grime. I have new boots on the way from clay. I'm running a edge evolution in stage 2 with stock exhaust with muffler and cat delete. S&B air intake on the way also.

 

I would start with pulling the codes, can the evolution pull them?

Could have just been either a P1211 ICP lower/higher than desired, or a possible overboost code.

 

I think I may know this one... but it's way too early to start dusting off the Buck$Zooka. When you're "on it", the HPOP really has to step up. If your tuner creates a scenario where the PW can go too wide (or the HPOP is weak), then the IPR goes nuts... trying to raise the ICP. As soon as you let off, ICP spikes. This would set a low and a high ICP code.

 

I hate saying it but I bury my head in the sand on this. Mine will come on under the same curcumstances, and goes off quickly, runs fine.
I don't have AE handy so. Has been doing it last two summers, only difference is now it doesn't de-fuel with the DP 60t.

 

I will see if my edge will do codes later and see if any thing shows up
