**TESTING ON OPEN ROAD BY MYSELF***

35mph I did a 2nd gear pull till about 6500rpm and shifted, Everything is good. 47mph I did a 3rd gear pull, about 5500rpm my car went BOOM but doesnt die. Still running. Try 3rd again.... BOOM, but still running. Tried it one more time and POP again. I say fuck it and shift into 4th and go again and BOOM intercooler pipe blows off :(. The clamp flew off somewhere so I went home and called it a night. What I don't understand is why it was popping.

Fuel cut?
I rewired the pump with a relay awhile ago and it never did this before, even when it creeped to 20psi.

Pulling timing?
Supra SMIC so I don't think it is that.

Boost leak?
I just installed a new silicone hose but it is possible it was leaking since that is where the intercooler pipe popped off.

me=confused.
