ok i hit 9psi and then around 5500 it slowly drops back to like 7psi at around red line. is that normal or do i need a helper spring?????

Assuming you're using an MBC or straight up wg can - a helper spring can resolve some of that. It helps to make it adjustable (threaded rod) so you can make changes to the spring tension.

Has anybody just replaced the can? I do have the helper spring and all that, but sheesh.

I've recently been fighting this same battle myself, in the quest for a nice, consistant 14 PSI or so. With the MBC alone, my setup typically will spike to 15 and then settle down to maybe 11 or 12. Ridiculous.

I've done a preliminary helper spring setup, but all I seem to have accomplished thus far is to move the spike upwards a bit.

I used what I felt was a moderatly sized spring, not wanting to go too tight right outta the gate. I can't really say that it helped much- I'm still spiking... Base boost (with the MBC bypassed) went from about 5.5 PSI to 9 PSI. Relatively speaking, are others using stronger springs than this?

My helper puts my unassisted boost to abou 9psi as well.

I haven't gotten anything close to flat. I was seeing ~2psi fall after peak boost. The helper spring reduced that to just over 1psi.

I joined while back helping my buddy with his 91 turbo. I sold my evo 9 went with a gsxr 600 now im rocking my turbo miata.. And how can you hook up the mbc feed to the coldside of the intercooler? Just drill and tap for a 1/8npt barb in the piping after the intercoolerm before the TB.. I did it a while back and got another 1.5psi till redline..

Idk why you guys just gotta hack on someone just cuz they havent posted yet. Im not a newb. Lol ive been boostin for 5 years.. And tuning evos for the past 3.. Lets keep on topic from now on

3 years oh **** you must be a tuning legend.
Everyone tunes cars here. literally like 90% of the boosted people here. tuning an evo with ecuflash/evoscan is ******* cake. I'm serious.

Amak87, I think the thing that is most surprising is you pick a random thread, that's been dead for almost 5 years, and post a random comment in it. It's sort of like digging up a body to have sex with it, except everyone can see you doing it.
