Thanks, I will give that a shot.
I do like how the Forge BPV sounds even with the stock airbox still in place. It should sound even better once I get my intake installed.
What kind of BOV are you running?

resetting my ECU?!? how do i "reset" my ECU?? (sorry im still kinda noob at this stuff)
Also, is there a link someone can post so that i can hear the Turbosmart BOV?
Thanks!!!!
you are wrong....trust me, i did the testing for forge to get these valves set-up for the mazdas.
yellow is the softest, blue is in the middle, and red is the hardest. there is also a green spring that is way too soft for us and is not included.
here this is from forge.

i know it says the blue is for 23+psi but this is just an estimate. all cars are different and there are alot of factors involved.
where do you get your info from ?? you cant just make things up and tell people it is fact ! i did the testing.. i worked directly with forge to make these valves. the yellow is just like stock. you will get zero benefit other than a noise maker. the stiffer blue spring will actually reduce turbo lag. it forces the valve closed quicker between shifts, and really makes a noticeable improvement. it is also 100% safe. i get no compressor surge what so ever. neither do any of the others using the blue spring.
I still need to switch over to the blue spring, but I can say this, the yellow spring is an improvement over the stock bpv.
the numbers shown on the forge site are good baseline stimates ...thats all.
it is not set in stone. the rule of thumb for all bov's/bpv's is this....
you want it as tight as possible without compressor surge. this will give you the best boost holding, and fastest valve reacton possible. yellow works just fine, but blue is better !

So why not install the red one? I've tried the Blue, it felt like stock, The guidelines would have to be pretty inaccurate to say that Yellow would leak, and Blue would not, as it says the Minimum boost is 23PSI. We Max out (stock) below 20PSI, using the Blue one is not recommended for stock engines, as from the Forge website. I like the feel of the yellow one and I am sticking to that one, It does not all add up, the stiffer spring=better response? It would have to work harder, forcing boost out faster than it should be coming out, and resisting what little boost is coming in, I'm not understanding where you are coming from.
the red one is too stiff. you will get compressor surge...at least i did.
yellow will not leak, i never said that. you will have faster spool up with the blue spring. nothing works harder, it just closes the valve shut faster. the faster it closes the faster you start building boost. just trust me.

if by respond better you mean blow off more air, then you are correct.
but in a performance situation that is not what you want. you want it to release just enough boost to prevent comp. surge...but no too much. the softer the spring, the more boost you will vent. the more boost you vent the longer your spool up time will be. this is probably not too important for you though......you have an auto trans ! the stiffer spring will allow you to hold some boost between fast shifts, and greatly reduce your spool up time.
also the stock valve did not leak due to the spring tension. it leaked because the plastic can warp under high heat situations, and cause the piston to not seal well. i am not saying yellow is bad.. it will work fine. blue is just better.
if you dont believe me try it. this is my 5th turbo car... 2 of my previous cars i custom made my own turbo set-up. i know how this stuff works. if you dont want to take my word for it fine. did you notice all the others jumping in saying the blue works better for them ????
