Overrun Map With Cat ?

[Benjye]

Hiya ,

First post today and im impressed with the forums ! , I have searched and can't seem to find the answer ... If i flash an overrun map (ron98 with overrun) with the cat still in place is this going to cause any damage (both short and long term to either the cat or any other part ) ... btw after the cat its all straight through

Thanks in advance

f**k your cat royally. Some argument for damage to the exhaust valves in the long term

Over run with cat isn't going to do what you want ... Fire and bangs you will
need the decat.... 98ron on cat is fine... Tbh I've got a decat and it's crap the car felt smoother and much better with the cat in place... Glad my mot is due thurs so I have to put it back in ... And that's where it'll be staying

So essentially i need a straight through all the way for the overrun to actually work/not ruin everything .... im assuming that will be monstrously louder than how it is currently with the cat in place ?

Overrun/pop & bangs map is s**t.

It will piss you off, it will piss off everyone and anyone around you.

Dont bother.

I would like to try it and if its annoying i will simply pay the € 29 and remap the standard 98 ron
