Traction control... on or off?

[Adamt5386]

no traction control and a good set of tyres lol

I'm on MPSS and it's still a struggle! F*cking brilliant in the corners though.

haha I've got pirelli p zero and they stick well. although only running around 240 bhp

Yep, stage 1 was actually ok (around 300lbft). Stage 2 is a bit trickier.

ahh I see. I'm hoping to sort out my stage 2 very soon so I will experience that soon  I'm sure. just need to work out what exhaust downpipe to go with and map!

I went for a full Powervalve with sport cat and it's bloody brilliant. Looks good, sounds insane, and gives big power gains across the rev range, especially after the Stage 2 R-Tech map. Not cheap, but I'm really glad I did it.

I actually emailed r-tech earlier asking about state 2 map info as I've heard nothing but good things. although I hear I could do with s3 intercooler too? I've got a milltek cat back at the moment so with that I need downpipe and would rather sports cat than decat. and of course the diverter valve (won't even start mentioning that as I hear that's a sore subject on these pages) haha then hopefully ready to go!

The intercooler debate is probably more of a sore point. Some say a big upgrade is essential, some reckon the standard cooler is good for a k04 conversion with 2+ bits. I personally believe it's somewhere in between. I'm on the standard one and apart from on the odd hot day where I probably convince myself otherwise, it seems to be quite consistent. I don't do any track driving, and I don't sit in much traffic.

Maybe if you're on a 2+ map with the turbo maxed out you'll generate a bit more heat. But on Stage 2, and in my circumstances, I'm doing fine.

Just get a revision G dv or GFB DV+. Sorted.

Yes. Well mine is on the Leon anyway

Mine cuts the power (abruptly) when TC is off and when going round corners, so it still monitors steering angle.  I don't drive like that normally, I was just testing it!

APR shared a coding tweak to defeat the TC completely when off with VCDS but it wasn't accepted by my ABS pump. Not sure if it was just for more recent models of ABS pumps...

I can't find any definitive information, other than on 09 cars it's not defeatable at all, but on 06-07s you can disconnect the 'accelerometer module' or something!  Some folk say it's under the seat, some say it's under the cover at the passenger side of the dashboard!

oh I see haha sorry about that! I thought my standard intercooler would be ok for now to be honest. it's only a weekend car for me and not planning on tracking it anyway soon. GFB DV+ is what I have been looking at anyway so will go for that. heard nothing but good things. only need to decide downpipe for my cat back milltek. decat 100 cell or 200 cell.

I think the hardware recommendations on the R-Tech website are 'best case scenario' rather than minimum requirements. Plenty to prioritise before uprating the intercooler if you're in pursuit of power anyway. Fuel pump for a start.

decat, 100 cell or 200 cell.

I had a decat on mine; The sound was glorious! If anything it was a bit too loud and overbearing. But the smell was awful. I couldn't drive with my windows down, so it had to go.

I've a 3in 200Cell sports cat from Magna Flow fitted at the minute and i'm delighted with it!
No fumy smell at all. And hardly any drop in power from the Decat. It even passed the NCT (Irish MOT) emissions test!

ok that's great I will look into that then. I know decat is the cheaper option but I was just thinking about emissions tbh didn't even think about smell. think 200 cell is the way I would probably go. thanks for all your replies

^^ The magnaflow is cracking value at £100. Total cost including the cat itself and Welding 3in flanges onto it, and fitting it to the car was £200! For the fact that you're getting a clean smelling and emissions compliant car it's a no brainer!!

Here's a video to show...
1) Standard VW cat; which we initially welded 3in flanges onto, but it robbed too much power going from 3in to 2in and...
2) 3in high flow cat which we finally settled on...
3) Decat ... which was nuts, but too hard to live with in the real world...

If considering catless...there's a few vids on my channel with sound bits of my '07 K04. It's catless, 2.5" turbo back, and a single Borla.

oh that's a great price for a cat downpipe! do you know where I can purchase it?? I will have a look through all the videos later. Can't wait to get started on my stage 2!

[ducman77]

Car sounds great in the video ROH

Did you notice any smelly fumes from the exhaust when you got rid of your cat?

Here you go buddy.....

It's only the cat. Your exhaust fabricator would have to weld it into your system. Mine is after the downpipe on the straight section that runs to the back of the car.

Only £70 now....

[Adamt5386]

thats great mate thanks for that. just to clarify (I'm not ththe smartest) would I have to purchase a decat and then get an exhaust fabricator to add the sports cat to it? I don't actually know of any exhaust fabricators near me will have a search around
