Ok, here's some discussion:

Screenshot in which a minimized IE tab with the title "How to Take a Screenshot" is visible at the bottom = very funny. Almost as funny, in fact, as the time Hustler posted a screenshot with "GayFriendFinder.com" minimized at the bottom.

Next search = How to Crop a Screenshot -or- How to Take a Screenshot of the Active Window.

You never asked for help dickfuck, go back to starbucks and hang out with you snooty friends.

All I see is the word "discuss" in the OP

i said discuss, meaning critique it. does it look relatively close to a good map, or am i way out in left field. and wow, someone has a case of sandy vaginitis.

Pretty much everyone here tunes off MAP (KPa), not MAF. So a table of V vs RPM looks like chinese.

tuning ign looks like chinese to me. can you give me some pointers or theory, or some kind of guideline? 1.70v-2.00v is about zero psi. and i run 10 psi total.

If that is the case, why are you retard timing at cruise conditions? That will not help with power.

I tune via MAF, with the Xede, and still do not know MAF voltage in relation to boost level (since I use engine load not MAF voltage). Can you give me another reference point? Like 5V = X psi

4.00V seems to be my target psi according to a data log. so 4.00V = ~10psi. i say roughly because i dont recall if my turbo manifold was cracked and leaking for that run.

and im still learning how to tune and whats what, so whats cruise conditions? low/mid rpm and low/mid airflow?
