what kind of fuel are you running????? You just tune until knock threshold is reached. you'll probably get away with 20psi on 91 pump

 

[iammikesevvy]

93 octane

You should be able to get away with about 23psi on that turbo, then its going to push hot air with more. Basically turn up the boost and watch for knock, timing,and air fuel. Nobody can really tell you how much every car is different. Tune the car as best as you can.

You want some form of indication to where you are as far as knock goes. A/F gauge, EGT gauge, datalogger, etc. It would definitely be worth the money to invest in one.

21 pounds should be prefect for your set up

X2. You need to monitor knock as stated above. Every car reacts diff to boost but id say around 20 you are safe.

As for tuning I don't know how good you are with link but, look at dsmlink.com/forums. Have some great information on that website.

Run as much boost as you can before you start to knock. Then, either start to pull out some timing or lower the boost. If you don't already have a wideband. Get one. Make sure to keep your AFR around 10.5-11.5:1 while on pump gas.
