Default VF23 Boost issues...

I (well, Dubyarx and Scoob) just installed a VF23 last weekend...my mods are TurboXS turboback exhaust, godspeed uppipe, Samco IC hoses, TCG Motorsports intake, and a Blitz SBC-id controlling boost. Stock fuel system and stock injectors.

Everything was running fine (running 15psi) (a bit rich, but fine)...until last night. I did a WOT 3rd gear pulll up to redline. Then afterwards the boost came on very slowly and would hit over 7psi. I pulled over, shut the car off....restarted and was back on my way...no boost issues.

This morning the car started exhibiting the same behavior, but this time the boost would creep up to about 13psi (very slowly)...any ideas?

That's my first step. I didn't check last night b/c it was running fine. I might run out a lunch to check things out.

Anybody else want to chime in?

I agree. There is something wrong with your hoses.

Sounds like a selenoid hose problem.

Well, I checked and it looks like the hose to the wastegate actuator was loose...I need to put a hose clamp on it, as the stock pressure clamp is on there loosely.
