Take it easy before the remap?

Are you going for a decat or sport cat?
Best mod I've done. Love mine.

Ok only because some people have said just don't go over 2000rpm and etc and to take it easy or it may go into limp mode!
I went for sports cat what about you? I'm pretty excited!

No, it won't go into limp mode. Worst thing that can happen is the EML coming on because of the increased flow - this will be mapped out when you go to R-Tech. And that's nothing to worry about in itself, just the ECU expecting values within a certain range. The extra flow exceeds those values, the lambda sensor tells the ECU, and the ECU thinks there's something wrong... but the ECU doesn't know about the 3" downpipe and big cat allowing the extra flow. Performance is unaffected.
I went for the sport cat too. R32 style with 35 degree tips. Sounds incredible, and gives a considerable bump in torque and power. It actually made my clutch slip, so I had to hold off on the Stage 2 R-Tech map while I sorted that - I was driving around on R-Tech Stage 1 for a while and it took ages for the EML to come on. A good few months. Then got the Stage 2, and released even more power! It's a great mod.

Ok awesome I'm not sure why people seem to think it will cause me problems.
That's cool I also went for the 35 degree tips too they look real good!
Was it pretty noticeable then even before the map? Thought the power and torque gains from a turbo back alone were minimal so that's good to hear!

Very noticable. I was on Stage 1 R-Tech when I had the exhaust fitted, and gained 15bhp and 20lb/ft straight away. Then with Stage 2 R-Tech gained another 10bhp and 25lb/ft on top of that. No other hardware changes apart from a Pipercross panel filter, which might have got me 2bhp if I was lucky! I've got the graphs somewhere.
Like Nige said at the time, it feels like a mini remap. What's your current hardware/software spec mate?

Wow that's pretty impressive!
How come you didn't go for stage 2+?
Currently I've only got stage 1 r tech on my eddy but will have the powervalve and Revo intake when I go for stage 2
I can't justify spending the money on an intercooler and hpfp for stage 2+ as it's already a lot of power through the front wheels.
I only really wanted more noise and realised that I'm stage 2 ready with an exhaust and an intake so it kind of made sense haha.

Well that's a good question. At the time, the idea of an uprated fuel pump and 2+ didn't really occur to me. I was happy with the idea of a minimal build with good flow and decent power. Stage 2 sounded good.
However (and don't let this worry you, but it's worth knowing), shortly after the Stage 2 map I started getting fuel cuts. Basically the map pushed the standard fuel pump right to its limits and it'd occasionally fail to meet the fuel requests. So when a used Loba pump came up on here I bagged it up and with it fitted the fuel cuts were cured, with the added bonus of a stronger power delivery. When it boosts, it boosts harder, and more consistently.
I'm still on the Stage 2 map, and arguably I could nip down for a tweak to 2+, but the long term plan is a k04 or k03 hybrid. The way I see it, it's strong and reliable right now, and I'd only really gain a little bit extra with a map tweak. And all these map tweaks cost money! So at some point I'll be doing turbo, intake and S3 cooler, then back down to Hinckley for Stage 3.
All I'd advise is that a Stage 2 map will be asking a lot from your pump. Be prepared for fuel cuts. And be prepared for clutch slip. Especially with your k04. You might be ok - some OEM pumps seem to cope better than others, just as some standard clutches do. But things can get a bit expensive once you start ramping up the boost

Yeah I guess I'm trying to go for a minimal build too with decent torque and power.
Oh really? Did you notice the fuel cuts straight away, and would you recommend the loba pump? Perhaps it's worth me keeping an eye on a second hand pump just in case! If I get a new pump and an intercooler then I may as well go stage 2+...this tuning business never stops!

The fuel cuts occured within a few weeks of going Stage 2, whenever I drove it hard. When I had the Loba fitted I wasn't really expecting any real performance increase but it's definitely added some extra shove when the boost ramps up. I'd imagine with the map altered to request even more fuel it'd feel even nicer. It's an underrated mod.
If I knew then what I know now, I'd have got the pump in before I went back down for the map.
AJP:
And yeah, Loba or APR are probably the two best uprated pumps out there.

Haha you've got me thinking if buying one before my remap now.

Managed to source a loba pump for £350 that's covered a claimed 1500 miles. Worth it?
