I have the 626 mani and notice the difference between the two, but I did a port match to gasket and polish job while it was off. It takes a little while to do it, but it also takes off almost an 1/8" wall around the inside of the intake manifold for more flow. Well worth it I think.
What have you done to your MSP today?

No not yet, when I do that I don't want to take too much material off. I'd like to do the head when I do that side of the manifold. Still up in the air with switching to the 626 so I held off.
You lose some low-end torque.

which is kinda good since the torque steer sucks, I like the 626, evens it out a lot, and gets a nice pull up top

I noticed when I got the 626 it cut it back a lot, and when I got the FMIC it cut it back also.. but before the 626 when I had the exhaust and other stuff, with the upgraded smic.. the torque steer in 1st and 2nd gear was horrible.. but that was when I smashed on the gas.. which in those gears wasn't that often, and I just did it for kicks here and there.. but yeah, now theres none. and it wasn't as bad at stock as it was when I had upgrades but with the smic instead of the fmic and a 626
What I meant was maybe one just for the MSP section. Having members, especially those who have extensive builds, post up their results to show show off and compare results.

as far as I know, only two people with extensive builds have dyno results on the forum and one of them is banned now. Signature Sound made like 397hp I believe and of course everyone knows Mazdaspeed2oo3.5 is somewhere around 500, shooting for 600. Other builds really aren't going for HP numbers.
Ah, just curious as to how much power certain upgrades will result in.

everybody's setup will yield different results as no one's car is setup the same. Plus, different areas, climates, altitude, car's condition mechanically, it will all play a big factor. When I first started modding, I searched and searched but had no luck finding threads with dyno comparisons. The only thing I could find is everyone's "butt dyno" results, which really didn't help. I actually had plans to dyno my car as I upgraded it, but I ended up deploying to Iraq twice and also multiple out of state training exercises. When I did have the time, the shop dyno was down for maintenance. Now my car is about to be fully bolted(and hopefully running soon.lol) and I still don't have a dyno yet.

Realistically, none of the tuning options (short of standalone) are sophisticated enough to yield consistent dyno results, and being a turbo car, to tune it correctly you need an eddy current dyno, and realistically for the power these cars put down its just not worth it for the vast majority of owners.
put mine on a dyno a while back with just a fmic and 10psi and made 130/130. lol
