have been in archives [zd30 di turbo egt] and was wondering wether I have set nads up correct. dawes/needle valve have been in for several months now and seems to work how it should. [it was set up by chaz link] I notice in some of the posts that hwy driving[100klms] a lot of you are running boost around 10 psi. my boost doing 100klms is 12psi . this boost will stay at this reading cruising down the hwy. is this what it should do. I thought it might vent off down to 5psi and start climbing again. maximum boost is 14psi. egt are between 250/280 degrees c. I am happy with the set up but just want to check.
