Message: [QUOTE="superpsd, post: 1431246, member: 15821"] I had been unable to spool the S369 since it has been installed. The gauge was only registering what the blower was putting out (10 psi) and I never heard the bypass open like the stock turbo would. I figured it's likely the 1.0 housing and a tune that has limited PW. After playing around in the factory calibration I found that the turbo spools crazy fast as I easily saw over 25psi and you can hear it when the bypass opens up. After playing with tuning I found that the issue was too far advanced timing. My base tune with the stock SOI map thrown in spools the turbo with ease. I need to light the fire under my heals and install more fuel pump and studs might be a good idea this next year. Also not that it's necessary but when it releases I will likely upgrade to Eatons new rotor pack from my 2300 to the 2650. It was shown off at Sema. Once VMP releases a Bolt on unit more displacement with higher efficiency is the name of the game.
