Going forward, I won't pay a "big name company" like APR/Uni for a tune. I suggest buying the OTS tunes from the Cobb tuners, because they're small businesses doing good work. I'm going EQT with my Alltrack.

On what tuning platform? I don't think Cobb offers 1.8 support.

Honestly, I didn't want to blow up my engine. It sounds crazy now but at the time and being a newb to the platform I erred on the side of caution. Oh well. You live, you learn.

Well many go Unitronic for this reason. Pretty sure Uni's tune has less boost requested than any other OTS tune. So you weren't wrong in your thought process.

I also went Uni for this same reason. And I also regret it, and would've gone APR instead but wasn't going to pay twice (even though I still hated the way my car drove, lol).

Just got rid of the car haha. Now that I know Cobb doesn't support the 1.8 ECUs, I'll just go APR 87 tune and run 89 octane lol

If you're going to run 89 why not just get tuned for 89? Otherwise it's a waste to pay for higher octane.

I'm not sure unitronic is actually safer though. Sure APR runs more boost, but I haven't seen a APR tune with correct fuel apply knock correction consistently. Meaning the APR tune doesn't knock. It runs more boost and there is more wear on the turbo, but how often are you flooring it really? The Uni tunes I've seen

Apr doesn't make an 89 tune.

Agree - I've got the APR Plus (therefore 87 Oct stage 1 low torque), have logged for knock on some flat out runs and never detected any. As mentioned here, APR is heavy on boost (up to +7 psi even on the 87 tune) but is that really the worse option Vs what must be heavy timing advance on the Uni.

I've done plenty of experimentation with up to 93 gas logging with dragy to see if there were any performance gains and found none, so nowadays I just stick with 87 as it is tuned for.

Is that the original version or the revised version 2.x ?
