Has anyone thats moved to a BB big shaft turbo on a stock long block experienced a big increase in turbo shudder when lifting off the gas after moderate boost around 5 to 10 psi? I've seen a ton of it since I've moved to the T66BB from my TE44 and today even installed a friends V2 IC to see if it made any difference and its the same. Even installed a BOV he had and on its lightest setting doesn't help at all unless your above about 17 psi.
If I pull out of my sub and hit 5 to 10 psi up to 45 mph then let off to 1/4 throttle to maintain the speed limit I sometimes have 5 full seconds of shudder which is annoying to say the least. Doesn't make it very fun to get in the throttle knowing this is going to happen every single time. I even removed the air filter and went for a short drive to see if it made a diff but no. Is it just the shear mass of a big shaft and being ball bearing trying to slow down and the reversion of all the boost in the IC causing this and there's no cure? Do I just need to suck it up and learn to love the sound?
Any insight for a possible solution appreciated,
Mark
