How do i get my rst to have less lag and boos sooner... it doesnt boost till about 3.4-4k and then when i change gear it takes a while to hit boost again?

Any tips?

 

sounds normal lol

bit more spec of engine or is it standard

 

either a smaller exhaust housing on the turbo, if it's not already a 0.36 that is.
bigger bottom end, that brings the spool revs down.
make sure it's mapped properly.

my 1.8zvh spools just over 2krpm and is on full boost by 2500-2600 on a 4x4 cossie turbo on a 0.48 exhaust housing with cossie down pipe.

 

collins -31 actuator,helps keep you get boost earlier,mine comes on boost just after 2k,

 

and a dump valve will help you come on boost after the gearchange
