BEGi reflash or new ecu for msm

-new to the forum-
i have a 04 msm and im trying to figure out what rout i want to go as far as tuning. i occasionally experience the famous BOG and would like to solve that as well as crank out as much hp as i can without sacrificing reliability. The car already has FM down pipe and exhaust, intercooler, BOV, and full intake. Im guessing its at around 200 rwhp. i would like to be able to turn the boost up to 10 or 12 psi if possible.![Party Kitty](https://www.miataturbo.net/images/smilies/birthday[1].gif)
i'd like to keep the cost as low as possible.
ive heard lots of people say "just get a boost controller and crank the boost up to 18 psi" i wonder how that could be the best option...

If we're being serious, there are a couple factors you should consider:
1) do you need to pass emissions/smog visual
2) do you plan to add/change/modify more after this
3) how comfortable are you about learning to tune an ecu
Notice I didn't mention price in any of these, because if you're poor you need to leave your car stock. Pretty dumb to be modifying a car when you're broke

When I used BEGi reflash on my NB2, it would run rich at WOT - like pegged 10.0 on my AEM wideband. If I gently roll on the throttle pedal, it's a little better - around 11.0, but still rich. Took it to a dyno and their wideband read 9.XX @ WOT ![eek5](https://www.miataturbo.net/images/smilies/eek5.gif)
I will probably Email Stephanie again about it since my last email to address the rich issue went unanswered.
It's one thing to consider with the reflash - you will have some downtime when you send the ECU back to them for adjusting.

I looked at a few different options too. But when it boiled down to it,
BEGI reflash is 700
MS2E from Rev is 880
So for less than 200 bucks you have a much better system. At that point you can either learn to tune it yourself, or pay someone to tune it for you. But at least you'll have a much better system.
As a matter of fact, I sent Rev a PM and he says, "Well the exchange rate is good, so you'd be in it for 800 bucks". Not in those exact words, but needless to say, I went ahead and sent him the money.
I was going to buy the bolt on's, but I figured (from my experience) that the car felt decent stock, but when I did the intercooler and down pipe (the two cheapest mods IMO) the hesitation/bog felt EVEN worse, so I couldn't imagine how much worse it would be with intake etc etc.

The XEDE harness overlays your stock ecu and you essentially have to 'tune out' the bog from the stock ECU. Doable non the less. It'd be a great starter ecu to at least play with timing & fuel. You want 12psi? The xede will get you there, will also help with emissions but thats not really relative.
Where the megasquirt comes in, you're given full control of what your motor does. The learning curve is steep, but the rewards in the end are grand. The sky is the limit.
Edit* Look here for MS Compare - http://www.mslabs.gr/mslc.html Reverant @ MSLabs - You can PM rev here on MT.net.
IMO I'd pick up the latest MSPnP for the MSM
