Evo IX reflash w/stock exhaust
I have an Evo IX and I was wondering what the gains would be with only a Flash (leaning toward dynoflash), no exhaust. I would like to keep the exhaust stock, for now. Also I see most people do a mbc and raise the boost to say 21psi, wouldn’t the reflash raise the boost already?

Dyno Flash said that I would see 25-35 HP on my stock IX with a street tune flash. That's what I’m doing when Al comes to Chicago at the end of this month. I like how the car sounds now with the stock exhaust and don't want it any louder. The car is plenty fast for me now but for $300 I'm going to take the extra power.
Is there anyone else with a mechanically stock IX that had a reflash and can comment on their experience?

I presume the MBC provides more tenability options to Al and maybe provides slightly more margined of safety/power? I've heard there are mechanical and electronic MBC - the electronic apparently can be more expensive but more accurate. If that's the case I go with an electronic version - what would one of those cost?
Any comments would be appreciated. Thank you.

stick with a mbc,hallman or forge unos. Al sells the forge and its a good unit so i would stick with that. yes Al can control boost with the flash but like it was stated already you would need the boost lines changed to go above stock psi.With the flash and mbc with the new lines you will see a big difference in power and especially driveability.good luck.

The lines meaning your boost lines. They have to be modified to run increased boost when using the ECU to control boost. The ECU can't raise boost on its own. Installing an MBC is simple and shouldn't be more than an hours labor.

With just tuning power jumped to 292whp and 293ft-lbs of torque!!
Boost spikes to 1.4 bar dropping to 1 bar by redline.
So here are the stats
HP before and after
262whp, 292whp after(30whp gain at peak)
256tq, 293ft-lbs after (37 ft-lbs gain at peak)
These results don't tell the whole story tough. Playing with the Mivec timing brings the turbo on boost quicker, and gives more power and torque in the lower to mid RPM range. Out of the 5 EVO 9's I've dyno'd I see a power dip around 7200rpm. With tuning this dip goes away and at 7500rpm I was making about 40whp more over the stock ECU program at redline.

All tests were performed the same day on the same dyno with the same car. All results are using the pump California 91 octane Andy drove in with.
Summary
Stock: 260WHP 253TQ - 17.15psi peak
Stock + Flash: 288WHP 280TQ - 22.71psi peak
Turboback: 301WHP 261TQ - 18.14psi peak
Turboback + Flash: 330WHP 301TQ - 22.37psi peak

This graph compairs the car stock vs. Harman Motive flash. Only modifications were the reflash and boostMOD (stock hoses and solenoid remain).

Needless to say, I was very impressed with the performance of the car. It's right inline with my Evo8 MR w/ cams, intake, etc.
Each map was road tested following the tune to confirm proper A/F, boost, and timing profiles on the street. All tuning was conducted using "det cans" (knock sensor and amplifier connected to headphones) to ensure safe tuning.
