The great big MK6 Golf 118TSI tuning thread

[The_Hawk]

Has been serviced once, plus end-of-warranty check recently.

Do you have the option to switch tunes? And do you switch back to stock for servicing? Or do you leave it on the performance tune? (and if so has anyone said anything?)

Visiting a dealer is just about the only time I turn my tune off, and is the actual only time I make use of Security Lockout.

Do exactly the same as Ryan R for servicing, plus removal of C.A.I.

Redhot,

who did your Stage 1?

I take it from comments above that once it's turned off/locked, Dealers can't "see" it.

Also, what is the process fitting your 18's... is re-cal of speedo etc something you did yourself. Much impact on ride/steering, and do you have any pics to upload. Also of chrome grille?

cheers

Have you guys heard of Protune for remaps? A rep sought me out and is offering to remap my 118 tsi mk6 jetta from 160 hp to 195hp and torque from 240Nm to 300Nm.

He claims that they take a copy of my oem ecu file and they modify it and since it is the modified oem file that is used in the remap my dealer won't be able to find out the car has been tuned.

He also offered another remap for max power of 210hp. They can go higher but the bearings of the turbo would be severely stressed. I'm very tempted to do the 195...

Never heard of them. Your dealer will know its tuned when they drive it

[Ryan_R]

Hehe, that almost deserves a

Now that I've got my new clutch kit it'll be interesting to see how long I last trying it out before running back to Volkspower for my APR.
Also in the Polo GTI section Guy_H mentioned there's a new ~$1000 DSG tune coming soon (this week?) that doesn't shift up so early. Not APR branded and not able to turn on/off like the engine tune.

Ugh. It's my first car and only had the 1000km service done so didn't remember the tech takes the car out for a test drive.

Armed with this new "info" i'm going to ask Protune about this and hopefully make them squirm lol.

Protune is based in the uk by the way but seem to be branching out. Trinidad was the last place I thought they would come. Figured they would go to Australia first.

When it comes to tuning there are a few schools of thought when it comes to VW service people.

The line "they can't tell" has a few caveats in most cases. AFAIK what they mean is that it doesn't jump out and bite the technician while he is changing the oil in your car, nor does it set off any flags/warnings when the tech scans your car for errors. In the vast majority of cases your car is unlikely to break so the "normal" services won't have to look any deeper so they have no cause to look any harder. That said, he may notice that things seem a little strange during any test drive, but then it depends who actually drives it and if it's just between the car park and the service bay or if it's further.

The reality with tunes is that when a tech who knows his stuff checks out some of the logs and notices it boosting to ~1.6 bar instead of the stock ~1.0 bar it might just set of some warning lights in his head In short no it's never going to be 100% hidden.

Of course you could always use the company who tunes your car for servicing, that way there is no need to "hide" anything and they can be aware of all the factors when servicing. Plan B, if you have the ability to switch things back to stock, do that then get it serviced at the dealership. As I said, they can find it if they want to look hard enough, but if you don't draw their attention to it it may very well go unnoticed.

Bottom line, you are toying with parts of your warranty, get informed on what the potential implications are and always remember that in the absolute worst case you end up with an engine you have to replace/rebuild out of your own pocket (of course you can just consider that the chance to build it bigger and better!)
