also at like 4500 im getting at the most 10 psi of boost
so i just started to mod my g60, i have 68mm pully, 3.5 bar fpr chip, isv, and rsr outlet. After i put all the stuff on i started getting wicked idle surge went over everything and haveno leaks, the car ran fine before now have the damn surge.
Any help would be great
also how much psi should a stock charger with 68mm pulley put out?
How do you know you don't have any leaks? Did you do the proper idle screw adjustment procedure? Ignition timing done correctly? ECU vacuum line plugged in and exactly 1 meter? I would grab a spare known-good ISV and try that (or test it by maintaining your own idle until it warms up with it unplugged). Blue temp sensor could cause weird problems like that (also plugging the wrong harness into the blue temp sensor). Check your idle switch adjustment on the throttle cable and the WOT switch functionality. That is everything easy I can think of.
