Hi guys!!! I´m planning to install a electronic boost controller in my bpu Evo IX,and I want to know what is the max boost that I can run without reprograming the ecu or changing to speed density,of course on pump gas.

Thanks in advance

 

Huh? Max boost is not relevant to the ECU or whether you run speed density or a MAF. It's relevant to your mods, octane, and tuning.

Please search.

 

You can run your stock boost level............ until you get a FP then you can do 22LB

 

i got a buschur 20g and im runing 26 lbs on high and 22 on low. and i got stock ecu. dude that doesnt matter about holding more boost. get a new turbo and etc. then get a reflash from jestr using evoscan or mitsulogger.. i gained 50 whp through him, hes the man!!!
