dude not only should you not get a Stage 2 IS12 tune, you shouldn’t get any more tunes from Uni. They’re underwhelming.
the APR 87 octane IS12 Stage 1 tune I have on my otherwise stock 6MT Alltrack is much better than the Unitronic 93 + 91 octane tunes I bought for my previous MK7 GTI, and I also bought a DSG tune for that car which sucked. Uni stopped investing in this platform in like 2017, and APR has continued to update tunes. If you’re going OTS I don’t see any reason to choose Uni over APR, Uniconnect be damned. The convenience isn’t worth a shitty tune that’s not worth the money.
