Hello just wondering on your mk5 gtis were does your boost cut in?
Just had a map put on my car (flash) I know but only temp.
And it dosent really boost downlow like I thought a small ko3 turbo would it all up top.
My mates a3 1.8 boosts low which is how I want mine

Dan_FR:
Too many variables..... It depends on what RPm you plant your foot, what gear you are in, and what sort of incline you are on for starters......

But it should feel very spritely down low as its a tiny turbo.

You either have a hardware issue, or a very bad map, or a combination of both

For example, Mine is Stage 2+ so I have more low down fuelling available for more performance, but my car can make well over a bar of boost by 2,000 RPM in a high gear if I load the car up... Day to day in the lower gears its spinning the wheels by 3,000 RPM

Ant b:
I assume it’s just that map tbh,it’s only temp till I go to rtech

pudding:
As above.  Throttle pedals as we once knew them were replaced with 'driver demand' modelling years ago.

Anyway, mine is similar to Dan's, albeit a KO4 engine.   If I nail the 'driver demand' switch to the floor at 2000rpm in 4th gear on a flat road, I see 20psi by 2600ish rpm and 30psi at 3000rpm.....holds it for a bit, then starts falling on it's arse past 5000rpm.  An intake would help that a little bit in my situation, but I don't want the noise.

Sounds like your map could be a little better.

Ant b:
Yeah it defo could,I’m not sure if I have a boost leak or not as this ra air is so loud
