I have just replaced my old stock worn out turbo with a new upgraded one! Probably What everyone would Call a stage 1.
After it was fitted the actuator (-31)
Was set Way to High, and the car would boost at around 12-13 psi (Got the AEM digital boost gauge)

The boost have been decreased, but the plan is to run 15 psi when the car is ready and when i have the money for a tune.

I thought that i had a Stock ecu and needed to get a chipped one, but as far as i know the stock ecu is not able to run that high of a boost level?

I believe that I've got a 90'spec ecu, but my question is, how many psi is possible on a stock ecu? Is it even possible to get 12-13 psi with a stock ecu? Or have my ecu been chipped by the previous owner? Would love to save a few hundred pounds on a tune!

Cheers😃
