Default High egts really confused now

Hey guys I've asked about this before and now I'm really confused.
I'm running really high egts going Down the road and when I barly get in the throttle.
Everyone and myself was blaming this on my hx40 turbo I have on top. But my buddy just rebuilt a 12v and put it in his truck. He also threw a ht3b under his hx 40 . Same setup as mine. I preached to him for 2 weeks saying hes wasting his time and he's Gunna have the same problem I have. Now his motors running and it runs smooth and about 650-700* down the road. We have the same setup but his is running right and now I look dumb for saying it wouldn't work. So what could be my egt problem? I not ruling out the turbo. But his is working fine with it. Any help appreciated I want to figure this out

Have you checked to make sure both turbos are moving freely? What are you running for a air filter?

Bhaf. and when I had my 35/40 hybrid up top it had good cruising egts. There bad when I put on the 40. So I'm blaming that. But my buddy's got the same setup and his is fine. His is lifted with bigger tire to. I switched to 410 gears and it never made a difference. Should I look into my pyro? It's out of Warrenty. Idk what to look for
