De-cat Power / Effect re-map?

[Motoract]

Hi their.

I'm thinking about getting another cheap standard exhaust off a breaking fabia & thinking of doing a de-cat simply for more turbo whistle & maybe a tiny bit more power

my question is, I've already had it mapped, from 100bhp (PD100) to 140bhp, will having the de-cat effect it at all? if it made no power difference, I really wouldn't be bothered, I'm just after the turbo whistle, but I dont want it to make less power because the gas's are escaping out faster than they were before, therefore messing the already adjusted fuelling/air from the re-map??

can anyone help?

Cheers!

I had my cat cut out of my exhaust and the only difference was LOUD turbo, no power difference. (Y)

Ive read mapped then de-cat is bad for the turbo

De-cat then map is fine though.

Bear that in mind - the DPF/car bit!

how can it be bad for the turbo? tbh, if the turbo did go bang in my car, all the more reason to swop out for a bigger one :p

The MOT bit wont effect me, by the time the next MOT is up, the car will be sold, but thanks for the heads up!

No worries.

Something to do with a lack of back pressure, leading to it over spooling, or spinning too fast? Something like that, but I've not got a turbo, so I don't really pay attention to the details.

That is what I was thinking, I've emailed RS tuning who mapped the car, to see their reply, but I just so happen to have a downpipe lieing around, so might try it one day for the funnys!

Anyone else any experience with it?

But I didn't have it re-mapped to drive like my Gran....

I`d be inclined to stick to the jabba line of what was said about, decat then remap is cool, but remap then decat can cause issues.

does your gran floor it at 1000 revs? does she redline it? let me know when you've asked.

No but she's bloody good at slipping the clutch, does that count?!
