Still hitting boost cut at 9lbs

Post by cintegra98 »

Ok I am not sure if I did this right but just let me know I am still learning and trying to figure this out Here is 2 datalogs we accomplished if correct during these runs. Also if either of the administrators answer this could you tell me how much a 3 bar map is with pigtail. Thanks for the patience as this is getting frustrating I like your boost cut feature for the saftey of it but cant really experience my cars full potential.

At the time you had a boost cut, your boost was more than 10psi. Maybe you are having a boost spike.

They have a price list. Check it out.

Ok could you please explain where you saw that, or what I should be looking for, someone else on this forum told me to datalog and see what my map sensor is reading but once again I am trying to educate my self on these problems. I did see in the graph portion where it seemed to go out of the graph. Is that what you were talking about. And if so what type of things do I need to address, I have read so much on this, not sure where to start. I do believe that I have too many tees in my setup so I am looking at a vacuum manifold to help out. Also my wastegate(internal) seems to have a threaded adjustment on it. I have read long throw and short throw for this adjustment, not sure which way to adjust it. At any rate thank you for the info.
