weird idle/ vac problem... some what long.
This all started after installing the hondata running on a basemap (properly installed, even double checked everything agian)... idled perfectly on the old management setup (afc) with the same 450's and everything else.
Car now has a terribly labored/ searching idle and sounds like it has a intermitent misfire or whatnot ignition trouble, kinda that sputtery sound... anyways I touch the gas and the revs will come up and it smooths right out. When holding about 10-15% throttle steady the revs will come but then drop back like I am not even touching anything. When I let off the gas pedal the rpms drop and it almost stalls out... then they slowly recovers to the labored idle.
I noticed on my boost/ vac. gauge that the motor is pulling less vac. and will start floating around from 14 - 18. Car always pulled a solid 20 - 22 before.
I guess I should tell some of the instances surrounding my problem. I have no check engine, it is an f22b1, hondata s2b/ p28 on a basemap, 450cc injectors, stock map sensor... I even datalog'd it at idle if anyone want to look at it for anything, I am kinda new to noticing problems in this manner.
Sorry if this is kind of jumbled I am trying to include the mostly relivant information I would think could be helpful.
Could this be fudged timing? Could being too rich cause all this? Maybe the wrong options the dealer set up for the basemap? Any suggestions? Anything... PLEASE.

basemap... although I was under the impression that 450's are nothing crazy, the dealer was very confident it would idle pretty well.
My car hardly runs and has yet to be moved since this... I would like to get it tuned but I cannot even get the car to them like this.
