Great stuff you will enjoy the R-Tech experience. . . Even Rich83 & TFSIMike are planning a visit now

Very nice mate, it's interesting to see how much difference the HELP makes, originally I didn't think one was necessary but glad I'm going for one now.

Hopefully they'll do a RR day or something next year, would be nice to meet some of the people and see the cars in the flesh.

They usually do a charity rolling road day in the summer. It's good fun

Do you know what boost levels you are running on those R-Tech 2+ maps ? To get that level of torque out of a K03 you must be running some crazy high boost levels in the mid range and that doesn't leave much room for seasonal temperature variation (i appreciate the UK doesn't get that hot) and driving around areas that aren't really at sea level. Was pretty sure I read the warmer the temp and the higher you go elevation wise , the more boost the ecu has to dial in to make the power, so if you're already on the limits , then what ?

I didn't see anyone mention the RS4 valve in their mods list, I thought that was a prerequisite at 2+ on a custom map.

Have read nothing but great stuff about Nikki's work so it's a genuine curiosity especially as not living in the UK I can't get an R-Tech map

The RS4 valve is for the K04 guys, I didnt know about the effects those things had on the boost levels. There's plenty of cars running R-tech stage 2+ and I haven't heard any horror stories of them blowing a turbo on a hot day so hopefully mine will survive  . If it does break my K03 then maybe I'll have to just get a K04

A well calibrated map from Niki will no doubt be correctly calibrated to account for changes in temperature (IAT) and atmosphecric pressure

mine was mapped in summer
so prob even more bhp now in the cold ! lol
certainly feels more bhp in this weather

Just a shame you can't put it all down

Thanks for the clarifications, Nikki certainly seems to be the guru from the various posts I've read on the web.

yes true i do try tho lol

Some serious figures in here! Very surprised but excited lol!

Sorry to hijack the thread but thought I would post as I am looking to do the same thing. I had my Mk5 GTI mapped by Niki in the summer and made 255bhp 316ft/lbs with just the 2 cats removed from the exhaust. Now I want more power but I am so torn between going stage2+ on the k03 or stage2+ on the k04!

Would be great to hear your views and opinions guys!

Thanks in advance

^^^^ Given a choice, there's only one......... K04......next!!

[GrayMK5GTI]

K04 is just better   

If you want serious power then K04 is the way to go, such a great turbo for response & power band 

As I've said in other posts too, it's better for traction as the power delivery is typically smoother and further up the rev range whereas K03 spools almost like a diesel turbo with huge wad of torque low down making it easy for the wheels to break traction

Im currently running a stage 1 r tech and cannot wait to go stage 2+.....its an addictive game!

I can't wait to get down to R Tech on Wednesday. I've no idea what figures to expect, but I'm looking for more midrange torque. I've had a custom map on for 70,000 miles now and it's always had oodles of top end power and really takes off at 4,000rpm, but it'd be great to see that power come in at 3,000rpm or lower if possible.

I'm running: ITG Maxogen G60, Loba HPFP, Forge Twintercooler, Longlife custom TBE w/200 cell sports cat. R8 coilpacks.

I must say, even though the car has been polybushed front and rear, so was stiff anyway, the recent introduction of 034Motorsport Density Line engine/ transmission mounts and Vibratechnics subframe mount/dogbone bush has made such a difference to the power delivery. There is literally no movement, the car handles on rails. In a way the power delivery feels a little less exuberant, because it's smoother, it's not, but it feels like it. I also noticed being able to get on the power quicker after fitting the uprated Neuspeed crankshaft pulley.
