I installed a Duttweiller Neck on my stock 87' GN intercooler. I understand this will increase boost about 2 psi over stock setup. Now do i have to adjust anything like reduce the boost pressure back to stock to avoid detonation/knock.
I understand that this mod allows the turbo to not have to work as hard getting air through and helps it spool sooner but I am concerned about the higher boost causing knock . Can someone explain what i need to do now ?
I have a boost gauge and a computer analyzer (OTC) but will the increased boost hurt anything. I think I remember someone saying to install an adjustable wastegate lever to adjust the boost or would a custom chip adjust the boost instead of the adjustable lever?
The car has all stock components including the original computer chip but does have the following - fuel pump hotwire set up and Walbro fuel pump and adjustable f/p regulator, K&N Air filter in stock location.
