Hi everyone this has most probably been covered before I'm thinking of getting a stage 1 remap on my 2023 Octavia Vrs petrol . I've been looking it up and some people say I need a DSG tune as well is this true? any help would be grateful.

While you don’t technically “need” to get the TCU done along with the ECU, it makes sense to do so. This is from both a standpoint of completing the package, so to speak, in addition to increasing the clamping force of the clutch pack to cope with the increased torque.

A custom tune is best for the engine - Ecotune, R-Tech, QST, Unicorn are some good examples. As for the gearbox, you’ll want to get a TVS map put on there - simple as.

Getting the ECU mapped and not the TCU is sort of like going to the gym and only working your upper body. Sure, it’ll look good and be a change, but it’ll be unbalanced - you want to do the lower body to really get the most out of it.

Thanks OccyVRS it make sense just didn't know if I wasn't getting wool pulled over my eyes or not.

No, it is absolutely worth doing. To cut a long story short, I currently only run a TCU tune on my car and, honestly, it's absolutely fine. I must get up to Ecotune sometime soon...

Where the wool may be pulled over your eyes is for the supporting mods. For a simple remap, there is no hardware required. Many people will do an air intake and whatever else, but the truth is - there's no point. The only restrictive part of the intake (not at Stage 1) is the elbow, and that can be sorted for £100. I have an R600, but anyway.

Ditto with the brakes - the stock system works very well up to 400bhp. You can't increase stopping power with 340mm discs on 225mm tyres.

Thanks for in info OccyVRS
