Boosting problem???? LOST!!!!

[NisanS13turbo]

I am using a MBC and turning up the boost or lowering it, im still boosting at 10psi. Right now I am currently using an blacktop ecu E5 I beleive. I was boosting 12 to 13 with an redtop ecu 62-63 and right after I replaced the ecu to the blacktop it stayed at 10psi. So now is this causing from the ECU or is it with my wastegate??? My next suggestion to do is swapped back into a redtop ecu and see what happens but what do ya thinK????

boost controllers only increase boost from the base boost of the wastegate spring.

What would cause my boost to active the way it is???

switch back to the red top ecu as soon as possible. The black top ecu has a different pinout wich will affect the fuel to air ratio wich in the long run mess up your engine.

it's different at the o2 sensor. repin and it's done.

Wow, this is terrible, um...so that is why its messing with my boosting and i backfire more nowadays.

How do you repin at the o2 sensor? After I do get it repin, will I be able to boost normally?

you repin at the ecu.
