I'm pretty sure its about 16 Pounds of Boost? Someone correct me if I'm wrong.

Probably somewhere around there

14.6 to 14.8 PSI net. The CPE pug and play tune will be 16 PSI net.

15.6 psi at peak....tapers to about 8 psi at redline.(doh)

15.6 is the actual Mazda DISI MZR spec, but not actual net. Best I have seen is around 14.8 effective in the engine logs for the CX-7. The CPE tune will be about 1 PSI higher to net 16 psi. I have seen a few dyno runs on MSP3 and 6's and they peak boost initially to 18 or 19 PSI for a bit then fall to around 15 PSI or so. And, I think the slight detune on the the CX-7 changes the boost curve a bit.

Is there a product that will Up Tune a CX7 to the 6?

15.6 is the boost on the MS6. The CX-7 max boost is 14.9 psi. A/R Value is 12.7mm and Turbo Inlet size is 41.7 in.

Computer reprogramming units are being developed, however it appears there are physical differences in the turbo unit or the piping leading up to the turbo unit.

There's also quite a bit of debate on whether it would be of benefit to make the engine in the CX-7 behave like that of the speed 6. Auto vs. Manual, weight issues.........

with 14.9 psi, do you find it necessary to install a BOV? thinking about putting it in and recirculating released air..

AWmustang, your planned mod is a Blue LED... any info on that?
