APR stage 1 surge

[Lewie_7.5]

All,

New guy here! I bout my car brand new last month and had an APR stage 1 tune installed the first week. Additionally, I did stock air box mods i.e. MST turbo inlet pipe, hose, turbo muffler delete, AFe filter and snow guard removal.

that said, my car surges in gears 2 and 3 during light pulls with the A/C on and ASR activated. It typically dissipates when both are turned off. Has anyone else experienced this?

Thanks in advance!

cheers,
Adam

No. Just got mine 2 months ago. Are you on stock clutch?

Could it be clutch slip instead of surging?

I’d inspect your air box mods too. Make sure lid is closed correctly, etc

Gears are too low.

Describe the surge better.

I really don’t think it’s the clutch. The car had 350 miles in it when I had the tune installed and I really don’t drive it super hard. The car currently has 2600 miles on the clock and the RPMs don’t climb/dive as they would with a slipping clutch

the surge feels just like you would think - it pulls and kind of loses steam, then pulls and back and fourth. Not super violent but definitely enough to notice.

And you have ESC off? You coded it to be off?

I’m thinking clutch or it’s the torque protection that is giving the unnatural driving feel.

Go ahead and contact APR. they’re very responsive on things like that.

I have turbo flutter in higher gears on my 1.8/IS12 87 octane stage 1 APR tune. Kinda bothers me, don’t feel that such a low torque, 87 octane tune should induce flutter ever

No, I just turn ASR off via the switch next to the shifter.

Highly doubt it’s the clutch. I’ve never driven it super hard and it only has 2600 miles on it. I have the shop that installed the tune calling APR’s tech service.

That's your problem. Traction control is cutting your boost. You need to code it out.

Might be worth it to try a throttle body alignment/reset.

With the mk7s does the gear indicator disappear while the clutch is slipping? That was always an easy way to tell if it was the clutch on the mk6. If the clutch was bad enough to slip in 2nd and 3rd with light throttle you'd definitely be complaining about the taller gears too, so I don't really think it's that either.

the mk7 does the same thing too.

It's 100% the traction control. I had the same with my uni stage 1 tune.
