Title: 1.4 tsi No boost in 1st and 2nd gear
Post by: Brodriguez on February 20, 2023, 02:46:20 am

OK so I've juat resolved my no boost issue. Found a vacuum hose that wasn't connected. Reconnected it and now car is boosting properly in 3rd gear and above, both low rpm supercharger and higher rpm turbo seem fine. But when I'm in first and second gear I get absolutely no boost at all at any rpm level. Any suggestions?

Cheers Brodie

Mate of mine has a 1.4 GT I suppose this is what you have ? Mechanic told him his turbo doesn’t kick in until 3rd gear that’s normal with these cars. Anti Lag map would fix this.
