IS 38 Turbo

Wouldn't fitting an is38 make your engine the same as a Golf R engine and therefore a Golf R stage 1 tune would be appropriate, or Golf R stage 2 if you're fitting a DP as well.

There are further differences between the two engines beyond the turbos, so a Golf R tune is not a plug-and-play proposition.

You can kiss the warranty goodbye on your engine and transmission.

so best option is to upgrade to a Golf R?

Thanks for clarifying that, I wasn't aware. I was under the impression that the Golf R was essentially a GTI with a haldex/4WD and an IS38
