thanks, was wondering why it felt like hitting a wall.

Oh and longer is less and shorter is more?

thanks

mine runs 19 psi but is decat and UK spec so no det, you can run more but a knocklink is a must for a JDM car and you will need a de cat to get the gases out and keep temps down

It's got a decat centre and "drilled" air box. so shall i start about 15psi?

start with a boost gauge an a knock link or you will be looking in the 'for sale' section for something altogether more expensive.

also read the 'dawes faq' compiled by the good Dr John Banks. Do a search- it will tell you all you need to know.
