I Have A Evo 8 Stock Just Kelford 272 Cams And STM Catback! I Put New Boost & Wideband Gauges And When I Saw The Reading Of Boost Its Hitting Only 12PSI We Check The Boost Selenoid, Vacumm Line To The Wastegate And The Wastegate Was Everything Good And The ECU Is Sending The Signal To The Boost Selenoid! HELP WILL BE APPRECIATED!

 

First thing I would do is perform a boost leak test.
That's probably the largest cause of not getting enough boost.

Feel free to PM me if you need any help with anything, or just call us.
Thanks!

 

It may be due to your latitude in Nortern Mexico.

And When I Get it There Ill Try A Boost Leak Test!! Well See If Its The Altitude Back Home Is 0 Meters Over The Sea Helping Us To Run Good

 

boost leak is the worst in these cars... it seems like there is more wrong than that at the time, but everytime i fixed the boost leak issue the car was right back to being amazing

 

Yeah Am Looking Forward To Do The Boost Leak Test!

 

I was just pulling your leg with the latitude comment. Sorry, rado

Defiantly do a boost leak test, easiest troubleshooting thing to do imo
