Hey guys, I got my wolf 3D on friday and noticed it has full electronic boost control, mappable every 125rpm................sweet. Anyway I definietly intend to use this serious function to its full and was wondering if you have any tips for mapping the turbo to drive like an everyday car in the low load, light throttle regions and then turn it into an angry mother of a beast in the high rpm/high load regions. I intend to run up to 14 psi of boost at the moment. Can you recommend a suitable PMW solenoid to run the wastegate bleed?
Cheers, sorry for all the questions Daniel Kroehn ----- Original Message ----- From: "LIEBIG, Peter" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, January 22, 2002 10:16 AM Subject: RE: Exhaust sizes (HELP) > Andrew, > > Ahh, the people you run into on the Ozdat list eh! > > GT25 is going well.
