    Yep. The torque output is the same on vag-com, haven't got round to doing a 'butt dyno' plot yet to see how the bhp figure compares but hope to do it soon.

    got my 150tdi anni re-mapped at jabba and it made 218bhp and 325lb/ft torque.

    I would have thought the 150 would have been quite Rapid ?!?!?!? because my 130 aint too bad, now makes me think what can i do to get more aswell, lol [:D] apart from a re - map

    For people who later search brakes and sizes etc and end up on this thread.

    I am running 240Bhp, 250ft.lbs and my 288mm brakes using Black Diamond discs and Ferodo DS2500 pads are fine, braking normally.

    I will be upgrading due to track work, but for normal and fast road use a decent set of pads and discs on 288mm are stopping 240Bhp easily. I should imagine they would stop at 195Bhp Diesel just fine.

    Thats from personal experience BTW...

    That's the problem dave...one can only imagine


    Don't worry Aphex, it's perfectly clear to the rest of the forum those members interested in inciting others by quoting the same old completely uninformed & boring quote.
    If only they'd actually DO their research, they might begin to not look quote so inept.

    Not going to mention brakes :lol:

    There seems to be some dispute as to whether a gt tdi 150 with only a remap can achieve 200bhp. As I said in my previous post, mine produced 187bhp on the rollers.

    Today I had a play with vag-com. Did some 2nd and 3rd gear runs and the figures produced were exactly the same. Here's what a 3rd gear run produced:



    rpm ft-lb bhp (ft-lb figure calculated from Nm figure produced)

    1281 43 10
    1323 117 29
    1365 142 37
    1428 179 49
    1491 208 59
    1575 242 73
    1680 279 89
    1827 303 105
    1953 303 113
    2121 303 122
    2289 303 132
    2457 303 142
    2625 303 151
    2793 303 161
    2961 303 171
    3108 295 175
    3255 289 179
    3402 283 184
    3549 277 188
    3675 276 193
    3801 272 197
    3906 269 200
    4032 267 205
    4137 264 208
    4263 254 206
    4347 244 202
    4452 232 196
    4536 221 191
    4620 210 184
    4683 201 179
    4767 192 174
    4830 186 171

    Here's the peak torque recorded (26Nm was at tickover):

    Here's the data graphed in Excel

    Now which is the more accurate, the rr figures of the 'live run' figures?

    Can we have a 6-way duelling match in Hyde Park to settle this? With everyone wearing tight red velvet breeches and using old muzzle-loading pistols.
    I think it would be the fairest way to settle things.:)

    Not for my own part Colin.
    I'm confident a 150 tdi 'may' achieve that.
    The point I raised concerns what can be expected, on average, from the majority of 'most' vendors. And that is, that the std remap is pitched at boosting power to no more than 190hp and not more.
    Of course the less inempt of us will realise the problems with claims like this and the variability of both cars and the measurement of hp.


    Can I being my .50 Browning m/g!?[:D]

    my input in the subject

    i've had 256's, 280's, 288's, 312's, 334's, and and I catagorically state that ALL off them are utter garbage. anything over 200bhp and you need proper 4 pots, even for road use. the mk4 is a heavy car.

    as for the power, i have personally witnessed a tdi anniversary hit 223bhp with just a REVO remap. even is the rolling road figures were a litlee exagerated, that's stil a genuine 200bhp+.

    It kept snapping CV joints though, and the tyre wear rate was a joke, it almost outweiged the fuel savings of running a diesel

    now stop female dogging will you.

    I know we digress a bit from the mapping topic but a remap won't make the car go any faster (unless limiter is raised) and it won't make the car any heavier so why would it NEED better brakes? I agree improving braking performance is a good thing but there's no logical reason for an upgrade just because you've remapped.

    What, you mean now you've added your 2p worth!;)
    Please note 2 things:

    -I stopped b1tch1ng about 20 posts ago. if you can call it that.
    -This was and could have remained a civilised and useful but for the attitude of newbies intent on treating the forum like a school playground.

    True, but not necessarily the whole answer. Consider this.
    Take a road of fixed length abutted by a junction and a nutter in said car. He will accelerate like a mad man. The extra power of the car means he will hit a higher speed sooner than previously. He thus should brake earlier but doesn't. He brakes therefore need to be more efficient to stop for the junction.

    just noticed this post. at the risk of adding further fuel to the fire, from my experience of remapping the car (its a 1.8T though) i really regret not upgrading the brakes before the remap. first impressions i felt the standard brakes were reasonably sufficient and i didnt feel it was dangerous as such but recently i did a big trip around scotland which confirmed i really do need the upgrade.

    as Sereph said..
    "The point is that you cannot increase a cars power by 1/3 and expect the brakes to continue operating maximally. It just can't happen."
    Exactly.

    id strongly advice the brake upgrade, the standard brakes are designed for the original power of the car. more power requires better brakes. simple. oh,and i achieved 208hp with a single remap. thats with a KO3s charger. i dont know what the gttdi is running.

    Don't agree with this statement (tho don't want to start another debate :lol: ). The manufacturer designed the brakes for the momentum (mass x velocity) the car could achieve and that won't change with a simple remap.

    I do agree brake upgrades are a good thing in general tho. I'd suggest a big trip round Scotland with upgraded brakes may have produced the same result.
