bleed vs. dual stage MBC

[The Pope]

well a true bleed, bleeds the map. Thats bad and leans the engine. Under bad knock the computer can pull back boost and lower it, has saved my engines a few times. With a G valve or any other MBC the computer can't save you from detonation.

How about a nice real computer with a 2 stage boost setting? My TU computer goes from 15 to 20 PSI on a switch. No fear.

get the valve from McMastercarr or Grainger its like $10, then add barbs to each end and you need a small orifice on the line that goes between the valve and the WGA(this is so the WG doesn't stay open due to the pressure traped in the line when the valve closed)

If you can find one for less than 10.00, then I would just buy. Going to a few hardware stores looking for the proper fittings and then putting all together.... All to save a buck? Like I said, $$8.00 WITH a 1 year warranty and it came to me = ftw

i just got the stage 3 cal from FWD.. so im trying to work with it but im having some problems with it so i want to throw a g-valve on it. untill i get one, im gonna hook up the dual stage. i know you're supposed to install it close to the turbo, but will it be bad if i put it in the car on the dash somewhere? just for ease till i can get the g-valve. so i dont spend all weekend trying to get it set right i can just turn it as i drive. how do i find out more about the TU cal?

I would never extend the hose more than 24" on each end. It could pose a problem with the WGC building pressure and cause turbo spike/lag. I usually just run up to my buddies shop and throw it up on the rollers and have someone I TRUST adjust it to how I want it. Doesn't take more than a couple attempts and a lot safer than running it on the streets at WOT to find boost limits.
