id get it flashed...wouldnt worry about the other s***...your probably gonna get a piggy-back or standalone down the road and that will fix the air/fuel and timing.
but the mean time get the flash....or get a fuel pressure regulator and tune it there.

The increased midrange power is noticable and should result in a performance increase (peak horsepower is almost meaningless - what's important is power over the usable rev range (the "area under the curve"), and the flash gives higher midrange power, thus increasing the area under the curve. IIRC, there's a pretty good (10+HP?) increase at 3500-5000rpm - do a search as there's a graph on here somewhere.
I liked my car pre-flash, but the hesitation was awful. I'm 4kmiles after the flash and lovin' it. None of the previous hesitation has returned.
Oh - for boost over 9psi my vote goes to forged internals first. Too many popped motors for my liking right now, so I'm sticking at stock levels, may add an FMIC if funding permits. Besides - the MSP has "adequate" horsepressure already!

Also, airflow mods (intake, FMIC, full exhaust) while expensive will add a good kick in the pants while still being safe. It will also allow you to run higher boost than you could without those mods, because they all reduce temps.

not to get off topic but what made you think that? did you hear it(detonation) i seriously doubt anyone couold hear detonation at that psi? what i mean is if your knockin at such little psi there would be no audible sounds...now if your pumpin 18psi well that may be a different story.ARunto said:
but how do you know?
Get the flash, the hesitation crap sucks. It made me want to pursue the lemon law. There was nothing fun at all about the MSP pre-flash. The symptoms existed both in city and highway driving.
You can boost above 6.9. You do not need internals or FMIC's to get above the factory setting. Get a 2 stage controller and keep stage 1 at factory levels and stage 2 at whatever works for you. Preferably less than 12. You have to allow for weather changes, ie spikes, so don't set it to high.
The MSP will make plenty of real world power in the 6.9 to 12 psi range. You cannot tell me that the Mazda R&D team did not factor increased boost in to the equation.
I am talking about sensible boost, not overboost/abuse!

your telling me you can hear detonation.....dude sometimes a person could be runnin and be detonating without a hint.wicked said:
but ok lets not make this into a detonation thread....
get the flash

dude so much noise comes from the engine its impossible to hear...especially at those rpms my friend...if anything check your plugs, theyll be the first to show signs.ARunto said:
like marbles hittin is what it sounds like....but the manifold makes that noise and so can your turbo from it being hot coolin down.

can you tell me what they looked like, pretty plz?ARunto said:
You can see the insulator and electrode had specks on it. Also as I said it is audible. I've done more than my share of dyno runs to tell if a motor is pinging. It did sound like a bag of marbles. It only did this at 9psi or higher boost. At 8psi it didn't make a sound other than turbo whine and intake noise. This is of course is my motor so other's could have different experience depending on weather conditions.

thatll do it....2 gallons of 104 octane man....makes a car feel good.ARunto said:
if you are thinking about a boost controller go out and get an electronic one. without it, you may have the boost set at 8 psi but your spikes will be in a dangerous range ~13 psi...
get the flash, get a fmic, get an electronic boost controller... in that order. exhaust should be added somewhere in there as money (and confidence) allows...
