ATR wastegate adjustment

[jack4954]

Can anyone give me details on how to adjust the boost level w/ the ATR wastegate. Its the large expensive (about $300) one.
I would like to get it down to 15 or 16 lbs as I'm running 92 & 93 octane.
Thank you & BLessings,
Jack

The ATR is available with 3 different springs, but we'll assume you have the 16# one. Unscrew (back it almost all the way out) the tensioner in the middle of the billet top until you just feel it contacting the spring inside, then lock it in place with the nut. That should do it. Having said that, I believe ATR now recommends the use of a bleed valve with their waste gates.
