as far as i know if i fitted a de-cat pipe it will affect the boost hence the need to remap the car but with my car having a hks boost controler could i get away without mapping it and just setting the boost via it?? cheers

 

Is this a Classic or New Age?
Generally the boost difference from a decat and the changes it makes to your existing map are insufficient to warrant a remap. Nice to have a remap but usually not essential.
Why are you fitting a boost controller? Do you have boost control issues?
Or what turbo are you running and what turbo do you plan to run?
Which ECU?

 

its a classic 98 sti ra has a full exhaust but still has the cat/cats its not that loud thats y i want to remove it the car is suspost to be runing around 380bhp has a zero sports turbo not sure about ecu dont know how to check!! but it does have a hks boost controler only reason i asked about the controler is i read that fitting a de-cat affects the boost cheers

 

dout its 380bhp

 

i dont know wot it is until i get it on the rolers but wen i bought it i was told it was 380bhp only been imported it was moded by zero sports in japan but i dont know what exactly wots been done to it

 

Decatting it will make a slight but not signifigant boost increase and not so much as your boost controller will notice.

 

ok dead on tanks
