Decat advise pls.
Hi all,
I've tried searching, but can't find a definitive answer, so... For a 96 JDM WRX ( pre-facelift, V2 ? ) got a HKS super drager cat back exhaust with a HKS mushroom filter and Bailey dumpvalve, Walbro pump, this is how i bought it. What i want to know is, can i fully decat it SAFELY as i know i the ECU isn't remapable? I've been told this makes quite a difference to response/performance, is this TRUE? Cheers :thumb: |
In a word yes ,decat will make the turbo more responsive allowing quicker spool up, as the exhaust gases have a less restrictive path to the atmosphere. Personally i would remove the dumpvalve after owning 5 various bov's (incl baileys) in the last 2 years,and nothing to be gained bar a noise ,but if your happy with it then ignore the last sentence.

Thanks for reply, so will the ECU sort out the fuelling itself ? Paranoid about it running too lean!
|
Has anyone else had any experience or advice on this?
|
full decat on mine reset ecu then have afrs checked on rolling road , no problem , the only prob you may have is overboosting due to it being more freeflowing
|
Sorry for my ignorance, but what is overboosting? what are the symptoms, and what can be done about it?
Cheers.,,, |
