i have a 95 wrx wiv tdo5 i want to increase boost what size boost pill/restrictor should i use for 1.2 bar ??? or do i need 1 at all has standard 3 port solinoide ??????

 

to be honest mate you will be wasting you time trying to increase boost to that level without either a modified ecu or a or a fuel cut defender if you use the later you better save for a new engine as just upping the boost to that level without any fuelling or timing adjustments will see you engine go BANG!

 

i have a mapped ecu bud its a prova tuned z4 ..has a higher fcd ..aggresive ign timin and i have uprated fuel pump

 

it will probably go bang then with 1.2 bar boost.

 

If it has a more aggressive map then I would be more wary of playing with it, more aggressive = less room for error.
If it can be remapped then thats what you want to do.
