Boost reading issue. Help. My car was originally tuned on the wastegate only. It's a SD tune. He got his readings from my 2 bar map sensor. It read at a consistent 8 psi he said. Since then I've added a eboost2. I pretty much left the controller alone. I set the overboost shutdown to 11psi. It's readying only the psi of the spring in the wastegate. It's reading anywhere from 13.8-14.7 psi. I don't know what to do from this point. I have the vacuum lines routed the same as the picture that I'll be posting. Can someone point me in the direction to figuring this out? I'm sure the 8psi I was making was accurate. I trap 126 with a 78mm turbo lq4 6 speed. I also raced the same guy before and after boost controller and the result was the exact same. So I'm pretty sure the eboost is readying incorrectly. Just don't know the steps in fixing it.

And was there not an almost identical query a few days ago ?
Presumably you tested as instructed ? What was the outcome ?

Plain English would be that the reading from the map sensor is way off from the reading on the eboost2.
I was hoping the weather wouldn't turn to crap but it just has. Temp dropping and all rain in the forcast. I'm going to tuck the car away and mess with it next spring. First step will be hooking a manual boost gauge to it so I can get a accurate reading and go from there. I'll revive this thread later. Thanks.
