For 7psi your numbers look OK, assuming it's a conservative tune.
You need to get the AccessPORT ASAP, it will change your boost-loving life.
Also upgrade ignition and put a midpipe (no cat) on. Then retune, at the same psi you will see probably 10-rwhp+ if not more, then you start cranking up the boost.
FYI, just because you have low mileage doesn't guarantee anything. All it takes in one strong detonation event and it's toast.

you in Ga?
the vacuum on a cold or warm engine? 17 will live.
check the vacuum at 2K steady state and no load--if its higher you probably have a small leak.
Charlie at Mazcare is the man to go too--if you need someone.
The timing is NOT suppose to be flat!!

at cold the vacuum is high.. up around 18/19 as it warms up it goes down. so i should put it in nuetral and hold the rpms at 2 grand? it should be at 17 still or shold it be higher than 17? i really dont know why the timing was showing a flat line but i think he finally got it worked out. thats what he said anyway, im planning to call him monday and ask a few more questions about what he ended up doing to the timing.

i actually checked on that a couple of days ago and my service manager told me that since they extended the warranty on the engines after i had already had a new one put in then my new one is under that extended warranty of 100,00. so i would assume the answer to ur question is yes. when i first got the new one put i they told me me i only had 12,000 miles/12 month warranty but a couple of months later i got a letter from mazda and a video that said my warranty was 100,00 miles.

Power!!
That seems pretty choppy at a smoothing level of 5. It seems like there is still some tuning that could be done to smooth it out. Other than that it seems consistent with the Greddy graph here (except for the PSI and total power)

It does look like the power peak is higher RPM range on your car then on this graph.

its crazy tho how much of a difference 7-10psi can make with the right stuff... i found a thread about gutting the cat last night and ima try that tomorrow just to see what knid of affect it will have on the misfire mostly. i still havent been able to pin point the problem with that. couple of days ago i threw a p0661 code so ima pull the upper intake manifold off and make sure the vac lines didnt come off that go to that solenoid. that is prob whats causing the low idle vac too.

Power!!
yeah ur right the power peak is a lil higher RPM... what cold that be acredited to? a difference in tuning? or the fact that our graphs arent going to be identical anyway.... and that graph on that post is kinda what i been going by leading up to my tune... i been kinda using it as like my "goal" sheet! (that was a great thread by the way.)
Edit: I went back and looked at the hp chart again and it looks pretty close (within 500rpm) so probably nothing wrong.
Although that said here are some things that can have an impact: could be due to breathing (intake/exhaust etc). That could be driving the decline in hp. If you have the greddy intake and your oem cat. vs. a better cold air intake and a midpipe or high flow cat. It could also be the tuning up above 7.5K. If it's tuned richer it would have an impact on power
I'm not sure if boost pressure has anything to do with the rpm range or not. Maybe Brettus or the other boosted folks know the answer on that.

i cant get it to happen at a certain rpm, but it usually happens when im at half throttle or less and not in boost. the only time i can get it to consistently happen is if im doin like 45mph and just put it in 6th and floor it.(not that i do that alot just wanted to see if i would get a misfire) thats when it will happen almost everytime. its so suddle tho, almost like a slight hesitation but my CEL will flash sometimes and thats how i know its a misfire. and when i pull the code its always on cylinder 2 which is really scary. it has happened on one occasion at high rpms too tho, but other than that almost never when im in boost or full throttle.
ive been seaching the forums everywhere for a solution and right now i jus been going thru a process of elimination based on other peoples dealings with misfires to rule out what it could be. ive put in bigger coils from a yukon, new oem spark plugs, and a bigger battery. i got some 10mm plug wires on the way ups right now. PLEASE any help or educated advice from anyone would be greatly appreciated.
and i know i GOTTA get the accessport just waitin til i have enough loot, which will be here soon on our christmas bonus. in the meantime i wanna try to get this mishap settled

is my acceleration ignition adjustment map supposed to be all "0's"? my ignition adjustment map is 3.5 at 500 rpms, 3.5@ 1000, 3.5@1500 then 1.0@2000. thats from left to right on the first row at -14.5. then going down to the next row its the same numbers at the same rpms but at -5.8, then if u go down again to the next row its 0.5 all the way up to 2grand thats at 0.0. these are the only values that have been filed in everything else is all 0.

if all else is checking out ok then check your fuel pressures--you may be having a drop in the pressure during the pump transition from a low to high speed mode---easist thing to do is to just put a new pump in. Fuel pressure issues are starting to raise their ugly little heads.
is it the oridginal pump that came with the car?
the vacuum thing is yes-- 2K hold it with no load on the engine(a/c off, lights off etc) that is always a back up procedure if a regular vacuum reading is in ?.
