My boost is crazy right now. My turbos won't come on untell very high rpms, at high rpms it boggs from 1 psi and then drops below to a vaccum of 2-3 while I'm still on the gas then it slowly builds boost to about 8-9 psi. My question is that if I do the non-seq should this fix my problems. Primary is not coming on at all untell I shift to next gear and let it drop below 3,000 rpm then I gun it and boost builds very fast to 13-15 psi. What is wrong. Should I do the non-seq. Thanks everyone. I have no mods

It is not certain if non-sequential will make boost more consistant, but I would try to track down the problem first and switch to non-sequential as a last resort. I would suspect that your problem is a C-clip that has come off of one of your actuators, the 3000 rpm to get 1st turbo sounds like it's probably the wastegate. If it's not a simple actuator connection problem, it has to be in your vacuum lines. If you can chase it yourself, do it, but if you are inclined to take it to Mazda to fix, save yourself the pain (time and money) and go non-sequential.

Start at the wastegate.

I'm having the same problems as you... sometimes I make 8-5-8 sometimes I make 2psi or nothing at all...

very good advice! Those pesky vacuum lines need to be replaced while you are in the process. If you go non-seq then you will only have to put 7 back in as oppose to ~70. Search to find more info on non-seq vs. seq
