So just wondering, how is MRC the master? MRC is certainly a great contributor but I don't get these sweeping statements with seemingly no testing to back it up. Don't say 'drivability'...we are talking about performance modifications here, so referencing something subjective is silly. Besides people love the drivability improvements of virtual all tunes so chuck that oot tha windae.

This is my third map I've had, I'm not naming the other company's, but from my experience and some what greater than yours, I would say in England they would be the best for custom maps, couldn't give a monkeys if you don't agree

Silas, I heard this before with maps at MRC. How does the sport and non sport vary. Mine feels no difference between the the two.

In non sport the car is much more dulled down, good for driving in traffic as the throttle response is not too sensitive, but in sport it just picks up much more quickly with a more responsive power delivery+ the limiter is lifted in the gearing

Day and night with the sport/non sport facility that I too, now have

Do JHM even offer custom maps in England?

If they don't then the debate JHM vs. MRC is irrelevant IMHO.

Why would you need a custom map for a car with stock cams, heads and just about everything other than the exhaust? Custom tuning sounds fancy but on barely modified NA RS4s I don't see the need (and the results bear this out). Don't say 'because'.

Here's a challenge. Show me an MRC tuned car that beats JHM. Custom tuning vs a very elastic 'off-the-shelf' tune.

Would be fun to see a challenge/comparo of sorts. 0-60, 0-100, 1/4 mile, 60-130 etc. Dyno if you must. For those who like the dyno, the JHM tune + exhaust cars here routinely do 360+ whp. This is about 40 WHP more than stock, freshly carbon cleaned cars. Apply whatever drive train loss you like to get that back to hp at the flywheel.

I agree they would be the best in the UK. Didn't realise the earlier proclamation that they were the "masters" was limited only to comparison within custom tuners in the UK .

I'd say their one of the best in Europe and by far the most accomplished in the uk. They also invest the most in product and platform
Development. I can't comment to much on jhm because I've never experienced any of their products other than a Ss kit and a set of brake discs that warped after a couple of hundreds miles

Warping a brake disc is a herculean feat. You probably had pad deposits.

MRC definitely help develop the platform which is very important. Not many companies are making parts for these cars, much less parts that work.

Right, even though this thread has gone a little off topic, I thought I would share with you what happened at AMD.

I didn't go for the de-coke as basically I didn't want to spend on that and getting the vacuum fault fixed. So anyway, after they replaced a MAF sensor. After this was added it got 380bhp on the rolling road, up from 349bhp on the same day (and 348 on the rolling road day).

I didn't realise how rough it had been running until I picked it up, now feels smooth all the way though the rev range and no more juddering when cold (which I always thought was my driving).

overall, very happy with AMD, I got a skoda RS (which was actually pretty bloody fast) as a loan car. They called me about the extra cost of the valve and were perfectly happy when I cancelled the de-coke.

I will be going back for a de-coke after christmas when I have got the cash to do it. But at the moment, I'm pretty happy with 380 bhp.... Feels quick enough!

After Decoke I would imagine you won't be too far off the 414bhp as we should expect. I had a vac leak sorted a good few months and couldn't believe the difference it made, so much smoother, no hesitance etc.

Did you get the black vrs courtesy car. It does fly, plenty of torque however did feel a little bit weird on and off throttle as it veered left and right with throttle applied and then released.

Warped disc saki they were tried on another car with brand new pads and suffered the same issue. Anyway this is off topic, amd have glowing reports as well I just can't comment on them as I'd never used them

[sakimano]

deposits on the used discs are only going to be made worse with new pads.

Yeah had the Skoda RS, I was really impressed with the speed, considering it has done over 130k I think its a pretty good runner! Although giving it some beans off the lights was interesting when you just sit there with the wheels spinning... Not used to that in the RS4! I would say that if I ever have to down scale in cars, then I now know that I could get a 2l and chip it, I would ever have believed that it would make that much of a difference until I drove it.

Hi Alistair,

I unexpectedly had to have the end of last week off so didn't see you when you came in to collect the car, I was sent pictures of the dyno results though. Glad the car is driving better now. Just to confirm your car had a vac valve and air flow meter, both made a obvious difference to the power and its delivery on the dyno. A de-coke should get you closer to the magic number!

Ben

P.S customers are generally always impressed by the Octavia! It does go well, especially for the mileage. It is a lot better than our courtesy Smart ForTwo we had.

Must have been the pad deposits then mate i forgot jhm products are indestructible

Or it was warped since you are never wrong

Here...argue with StopTech about pad deposits vs. warped rotors. Or pick any brake part company.

Myth # 1 – BRAKE JUDDER AND VIBRATION IS CAUSED BY DISCS THAT HAVE BEEN WARPED FROM EXESSIVE HEAT.

The term "warped brake disc" has been in common use in motor racing for decades. When a driver reports a vibration under hard braking, inexperienced crews, after checking for (and not finding) cracks often attribute the vibration to "warped discs". They then measure the disc thickness in various places, find significant variation and the diagnosis is cast in stone.

When disc brakes for high performance cars arrived on the scene we began to hear of "warped brake discs" on road going cars, with the same analyses and diagnoses. Typically, the discs are resurfaced to cure the problem and, equally typically, after a relatively short time the roughness or vibration comes back. Brake roughness has caused a significant number of cars to be bought back by their manufacturers under the "lemon laws". This has been going on for decades now - and, like most things that we have cast in stone, the diagnoses are wrong.

...

In fact every case of "warped brake disc" that I have investigated, whether on a racing car or a street car, has turned out to be friction pad material transferred unevenly to the surface of the disc. This uneven deposition results in thickness variation (TV) or run-out due to hot spotting that occurred at elevated temperatures.

Now that you've read that, next time you 'warp' your rotors, instead try this before binning them.
