Hi All,

Done my research and it seems that it can be quite risky fitting a straight through system on the newage imprezas without a remap, if I am correct in my reading then this is due to boost spikes? Can this be cured by a boost controller? just as I am going to be driving my car for around a month with the decat on before a remap.


Cheers

Not much risk de-catting the bug WRX with a TD04 turbo. Not a lot of a chance of a boost spike because the airflow is so small. All the ECU does is compensate as it's quite clever. Not a lot of change in BHP or spoolup. Just a bit noisier

De catting the STi is tricky because the larger turbo flows a lot more air and is prone to boost spikes and not recommended without a re-map unless you stay off boost. before re-maps people drilled out the STi restrictor pill to help.

Ah, that's spot on mate. Really appreciate your help!

 

Hi all, fitted my new turbo back decat today, sound excellent however I am now pushing 1.3 bar of boost... Is this dangerous? Only mod is an induction kit...

 

Hi there

Personally I would stay off the boost until car is mapped
