dont you need to recalibrate you maf tables when ever you change you maf.... i thought that the tables where specific to the sensors... with is why you have to do it before tuneing... i could be off tho... just a thougt

Maaaan, I still can't wrap my head around how you got your turbo kit so cheap!
Ever since I joined this site i've made it my goal to keep up with you but I still haven't saved enough!
Can't believe how far you've gotten :D
and how i've gotten no where :P

guess i just got a good deal? haha...ive gotten pretty lucky so far.
since last dyno day:
car is finally tuned to a stable state and runs great! thank you mazdamaniac! AFRs are rock solid. thanks to gregs as well, wouldnt be where i am now without him hes been awesome...thank you sir =]
only thing is my turbo is starting to get worn out...20k plus miles on it. but thats normal...so im going to need a rebuild/new turbo soon. anyone have one for sale???
besides that, had a small oil leak on the dyno apparently coming from my front seal if i remember correctly? been checking my oil and oil consumption seems normal. so the problem only happens under very heavy runs for now (aka back to back dyno pulls).
but yeah, if anyone knows where i can find a used or new greddy turbo please let me know =] (id rather just swap in a new turbo since this car is my DD and id rather not have the downtime)

looking to get some feedback about an issue im having with my 8
just for review, heres what i have on the 8:
greddy turbo with AEM intake
HKS blowoff valve vented to air
BHR coils
catless non resonated midpipe with hks hipower exhaust
stock spark plugs
the rx8 has been running great, changed coils, plugs, and wires about 7,000 miles ago and havent had any problems until recently. it happened a few weeks ago while i was driving. everything was running fine, then i did a small pull into boost and came to a stoplight. after that, i tried to go into boost again and thats when the issues suddenly began.
at partial/half throttle:
i am now getting some stutter/hesitation when i give it any more than 20% throttle around 3-5k rpms (AFR's peg at 11.2, it never used to go so pig rich with such light throttle and suddenly it does now). AFR's overall are going much richer than normal, even with light throttle, which may explain why its stuttering/hesitating. once i get past 5k rpms the stuttering/hesitation clears up completely but it still pegs at 11.2 AFR and feels much richer/sluggish than normal. right before/when the hesitation happens around 3-5k, the exhaust note sounds more noticeably raspy/harsher than normal. in the upper rpm range nothing weird happens and the engine sounds entirely normal.
at full throttle:
again, heavy hesitation from around 3-5k rpms due to the tune being waaay too rich (pegged at 11.2 AFR. it always used to peg at 11.2 before these issues began, but it never hesitated/stuttered so im guessing it went from ~11afr to around ~8-9afr now which is causing it to bog down). the hesitation clears up for a bit after 5k rpms but then around 6-7k rpms it seems to go extremely rich at full throttle and bogs down to the point where it wont go anywhere. thats of course where i let off the throttle.
other scenerios:
-Idle is perfectly fine when cold and when warmed up, no issues here.
-Revving up at neutral is fine and sounds normal.
-Start-up still seems fine (see video), starts up the same when cold and when hot. although i feel that at the same time that these issues started, the sounds that my rx8's engine makes righhhhtt before the engine fires up are different, not sure if its related or if im imagining things. the sounds im referring to are the three little "chuh chuh chuh" right before the engine starts. it does this when its warmed up and when its a cold start as well. here is a video of the start up: https://www.dropbox.com/s/2gicm24i9z...rx8startup.mp4
overall it just seems like my afrs go ultra rich now right when i give it any more than 15-20% throttle, it never used to do that before and now suddenly it all changed. help =[ i have not began troubleshooting yet.
here are datalogs of several scenerios:

let me know if there is any other info that i could provide that would help troubleshooting! thanks!

Same issues I was having, turned out it was a tuning issue and Steve Kan was able to tune it out.
But, generally boost leaks can make you run rich. So I suggest checking all your couplers and clamps real closely. make sure all your vacuum lines are secure and that your service port nipples are in good shape and on tight. Sometimes the couplers can split in spots and only leak under pressure so check them closely.

Making a boost leak/vacuum leak tester is a good idea, that is what we did. You can test sections by capping off sections of pipes. You can get pipe caps in different sizes from Home Depot or Lowes.

I'm going to say boost leak also as it came on all of a sudden, if you find nothing then it sounds alot like what recently happened to me except my was as soon as I installed BHR coils and got a retune from MM. Turned out I just need another tuning session and as I was running pig rich on the very early stages of my tune from MM.
My setup is very very similiar, difference being I am using stock Greddy intake rather than AEM.

I'm not sure what causes it but I have seen peoples tunes just get screwed up even without them making any changes to it or their setup. My only explanation for that is just the changes to the engines volumetric efficiency over time from wear.

Props to BHR for their insanely quick response time to my emails and the no hassle process for exchanging the coils i had!
How i found out it was the coils: I swapped out spark plugs, problem was unfixed however one of the spark plugs (Trailing plug from Rotor #2) was entirely black and looked very different from the rest of the plugs that showed normal wear and tear. So I then swapped out my BHR coils using another set of BHR coils from a friend (did not swap the wires), and the problem disappeared entirely.
Also, i have to mention the new tune i have received from Brett is incredibly smooth. all the previous tunes ive had before his were very jumpy and the transition between partial throttle and boost was not smooth at all, but with Brett's map, the transition into boost when i get on the throttle is seamless.
my 8 finally feels as if it came turbo from the factory with the new tune. feels like an entirely different car! thats how big the difference was btwn tunes haha. thank you brett
now i am ready for sevenstock!

Awesome man, it's always the simple ****. I try, and try, and try, to tell people that the tune is the most important thing in a FI build. But then people are like, "man you paid $500.00 for one tune?" and I'm like, I have spent more at a strip club in a couple of hours

Konig, glad to hear you got things resolved.
9krpmrx8, You are so right with that. Tuning with any FI vehicle is key. As i've been able to experience lately; it's even more important with these cars.

Yep, I have owned a few boosted cars and this is by far the hardest to tune with the least rewarding results. My girlfriend drives a Nissan Juke. When I started reading up and finding out what can be done on that little turbo 1.6L with just bolt ons and a tune, I wanted to cry, You really have to love this platform to stick with it.
