DTUK box on a Mk7 GTI GTD results

[GTI_Jeff]

The TSI engine in the MK6 is just as tuneable as TFSI imo.

K04 conversion gives around 370 BHP on a reliable rolling road.

I think people need to be a bit more realistic about what they expect...the IHI is a small turbo and isn't intended for out and out pace but spools quickly giving instant torque low down which is suitable in many driving situations in the UK.

Most VAG cars have a linear stock power delivery and will feel flat after coming from a remapped car.

The software vendor you choose will also influence this, some are more aggressive than others in power delivery.

Do you actually have any of the specs of the turbo in mk7 as I've searched and can't find anything..... How much different is the lump in the new S3 and new R as that makes 300bhp out the box. I'm guessing much like the ed30 and ed35 they run bigger turbo, injectors etc??

John, I am really interested to hear about how you get on with the tuning box. I will be putting one on mine as soon as I get the car too. How much did it change the insurance? (if at all  )

I have bought the box so I should get it end of next week so I will let you know how I get on. I have never bothered telling me insurance to be honest lol. Chance I will take. I can get it checked on rolling road and get a read out. But having had so many remaps I will know just by driving it how it compares to my remapped ed35 which was 310bph.

Do you enjoy driving without valid insurance?

An insurance company will probably take any opportunity they can not to pay out! It didn't cost that much extra to declare mine.

Listen if you want to tell your insurance that's up to you but I am perfectly fine with what I do. And regarding the mk6 it was not as tuneable stock with a stage 1 remap it was pish. Maybe yes changing everything yes. That is why vw stuck with mark 5 engine with e35 and the r. Hence the reason they have upgraded the engine for mk7 to make it more robust with extra torque.

It is indeed your choice but I don't think the risk is worth it. After all if you can afford a remap you can afford the insurance.

I doubt VW considers aftermarket engine tuning when it designs an engine. It is more likely down to timescales with engine development, VW had a tried and tested EA113 engine that could be dropped straight in without significant development costs.

If we are talking K04 vs K04 then the performance of the TSI exceeds the TFSI in like for like tuning situations. For example even stage 1 TFSI (K03 or K04) can benefit from a HPFP upgrade whereas the stock TSI fueling system is good to go for a K04.

The TFSI has been around for longer so has a longer track record.

It was not down to timescale. Thats why they used the mk5 engines with both ed35 and r it was built better to handle the extra power. The mk6 in current form was no use for the r. I had a few remaps from celtic tuning and then went to superchips and they all agreed that the mk6 was nowhere as good to tune as mk5. Hence the problems i had having to change a couple of parts to cure the overboost problem. But it was never fast. I had 270 bph on mk6 and the r stock my mate has destroyed me with some margin it was pish. Ed35 was a different matter with remap. Even without remap would still have beat my mk6. Horrible engine. But much improved with new updates to it

Yeh I agree in the ED35 and R the older engine would have been preferential because both engines had a variety of changes to accommodate the power increase. I was speculating that the TSI probably didn't make it into the R and ED35 due to time or development costs.

I can't see how it can be described as a poor tuning platform compared with TFSI (Like for like e.g GTI vs GTI), for example:

1.The TSI manifold's flaps lay flat, and out of the path of incoming air when not in use. The FSI flaps stay in the middle of the manifold which restricts the flow.
2.TSI head flows better.
3.TSI fueling system is better.
5.TSI engine compression ratio is lower allowing for more timing advance.
6.TSI engine achieves greater timing advance than the FSI.

There's probably more...some tuners are better than others!

A stage 1 MK6 GTI should match or even pull on a stock R from a rolling start but the R will beat plenty of cars off the line.

GTI Stage 1 - let's say 250 BHP, power to weight ratio of 190/Ton.
Stock R - 262 BHP, power to weight ratio of 181/Ton.

Maybe your car had some problems or the other car was modified.

I had the dsg and a manual and they were both crap. Sorry mate I don't know where you are going with this or what information you have Been looking at. It has always been a well known fact that the mk5 engine was far better to tune. Why would they bring out an ed35 after the mk6gti and put the old engine in it? Surely that has to answer your questions? If that was the case why bother using the old units at all. The simple answer is the mk6 was never up to the job of all that extra power and there is no tuning company that would disagree with me. I had 5 mk5s tuned with both turbos and no problems and drove much better than any of the 2 mk6gtis I had, hence the reason I got rid of them as they were far to slow. And my mates car is stock so I ought to know what is what. I raced him in both many times and got my ass whipped. So people that say an mk6 could keep up with an r are mistaken. Now the new engine has updated block to cope with extra torque. Why bother even updating it as if you say it was good enough?

Due to take delivery of a new Gti very soon and would be very interested in the group buy, didn't think the standard demo i tried was that much quicker than my Mk6 Gtd.

I agree mate I was very disappointed. You can pm me to arrange it if you want

Do the boxes affect your warranty?

No mate you just unplug it and no trace

I'm not technically minded when it comes to installing things like these but I could be interested as well
