GTI Lazy Acceleration

[lucas0]

Hi all,

I have an Mk5 GTI, with a stage 1 APR tune and GFB DV+. I recently drove a different Mk5 GTI, that was also stage 1 and it was noticeably faster to accelerate and felt like boost came on quicker. Talked to my mechanic who VCDS logged some stuff, but he couldn't find anything unusual (boost was all good). Car just feels lazy to accelerate, and basically never gets enough power to lose traction. The other GTI felt waaay more lively and you had to be careful not to lose traction in the front when booting it.

Any ideas?

Can you confirm it's been tuned?

Assuming you know for sure that its been tuned (how much boost is it making?) then you might have a boost leak or perhaps your timing is out and causing the laziness.

With APR tunes on the Mk5 GTI you can turn the tune on or off via the cruise control stalk. Might be worth checking the tune isn't deactivated.

100% has been tuned as I had it done during my ownership, didn't know you could turn the tune off, will check that out thanks !
