Hi,
All bought a 64plate Gti PP a few weeks back. Looking at upgrades all ready, seen there are quite a few mods now. Normaly tune breathing mods first then map last.
I heard on other forums that stage 1 maps see a good amount of power and torque, however the clutch can't cope with the additional torque. Any truth on this?
Looking at the following tuners for map.
Amd Essex as local
Regal Autosport Southampton
If clutch issues are a problem do they adjust the torque figures to prevent slippage.
Ain't been in the vag scene in a few years. So not clued up on these engines and capabilitys yet...
Thanks
All

Got the APR stage 1 on my PP GTI, done about 30,000 miles since I had it remapped, a little slipping is starting to occur.
If you're not going to hammer it around all the time and you're sensible about changing gears, your clutch will be fine. Having the power of an R is pretty fun, you will get a bit of wheel spin trying to get away from the lights though :cool:

Thanks for the info monsta.
Which tuner did you go to get mapped.

Mines a mk6 gti but the induction kit and remap transformed the car, I'd imagine it would be the same on a mk7.
If the clutch slips on the rollers then they will turn the boost pressure down slightly, my mk6 made over 270 but to protect the clutch it was turned down to 269
I've bought a sachs clutch and flywheel though so i can start playing again.

Will email a few tuners. Would prefer custom map than a generic one.
Motor only got 3,700 on the clock so clutch should be still strong.
Normaly go down the route with intake first Dv exhaust Intercooler than map last, on previous motors

Normally with VW's you'll go to stage 1 tune first as this requires no additional bolt on's and will provide the lions share of gains you'll get from the off. Most owners leave it at that point.
Induction kits might add a few ponies but you'll not really notice them aside from the additional noise and extra engine bay bling at this level of tune.
Same with the exhaust if you're going cat back only.
Next up is stage 2 which will require a downpipe, possibly an intercooler in summer, and then your induction kit might earn its keep too. This will give you an extra bit of mid range shove and a bit more top end too as the stage 2 map is optimised for the bolt on bits.
At stage 2 you'll almost certainly need a new clutch.
The GTI comes with almost Diesel levels of torque from the factory and the turbo spins up really quickly so you get peak torque at really low revs hence why the clutch can't really cope. It was never VW's intention that owners would shove another 100lb ft of torque through the front wheels.
Having said that, there are reports of standard clutches slipping, especially on R's (which seem to share the same clutch) where you have a little bit more torque to deal with and lots of additional transmission drag when under full load.
Even with the PP Diff the GTI struggles to put down stage 1 power at times. It's not so much the BHP but the huge amount of torque the engine puts out a low revs that causes the wheels to spin hence why there's a huge tuning scene with R owners but much less so with GTI's nowadays which is a shame.
My advice for what it's worth:
Get GTI home.
Immediately fit a pedal box as this alone gives you a better impression of how good the standard engine is, particularly in the torque department.
Shove some spacers on so the car looks better.
Once you've got a few miles under your belt and are familiar with the car and what it can do as standard (quite a lot, it's a very accomplished bit of kit) go for stage 1.
After that the next thing I'd recommend is another driven axle and a better flowing turbo which means you'll lose the incredible sharpness of the PP Diff but gain traction to cope with all the torque coming out of bends so you don't spin away all your power.

I don't hammer mine around too much but if I've been stuck in stop start traffic for a while before going for a longer drive (leaving a car show for instance) the clutch slips quite a bit. That's with a DTUK tuning box fitted.
Not normally a problem as I am properly boring slow driver most of the time.

Took mine down to S-Line Automotive in Ashford (it's local to my parents) as they are an APR agent.
Mine was the first GTI in the UK to have it done :laugh:

Thanks Exonian
For your info enjoying the standard form :cool:
Once I've put a few miles on will go down the map route first..
Just ordered my private plate for my birthday. :smug:

Mines staged 1 with the Racing line r600 intake, DSG though so no worries with the clutch slip. Mapped by my own company with a DNA tuning file, im in Medway in Kent if you fancy a ride I'll show you what you can expect.

Mines pp dsg remapped by revo technic stage 1 - performance is epic & on tap whenever needed!

Any noticeable MPG drop? :grin:
-
With mine mpg is dependent upon the through not that the car has been remapped, it can do the same mpg but there is a greater temptation to make it do fewer mpg
-
Comments generally as above on a run better mpg and don't really care when using the loud pedal!
-
Thanks for all your comments.
Spoke to Regal autosport they said they can tweek the torque to prevent clutch slippage.

Anyone had the revo map on a pp with a manual and not dsg?
