With all the talk of Overboosting...

Right o, here's one for ya guys.

Overboost theory with Hybrid VJ20/VF10 turbo and ported wastegate...

Part 1.
Stock mangagement, afm in place, stock dump pipe, 3" Exhaust, 2.5" intake piping and GTX intake manifold - Overboost went to about 14psi and stoped, very rarely hit boost cut.

Part 2.
Stock management, AFM in place, 2.5" mandrel dump pipe, 3" Exhaust, 3" intake piping, GTR intake manifold - Overboost was going through the roof, hitting boost cut all the time by 5grand

Part 3.
Microtech ECU, NO AFM, 3" intake piping, 2.5" mandel dump, 3" exhaust, GTR intake manifold - No Overboost. Didn't change any boost settings or vacuum lines from above setup and was perfect throughout rev range.
