Location: sittingbourne, kent | Problem with just tightening the pre tension
on the waste gate is boost comes in more gradual I find.
I have a manual boost controller fitted to mine
and I have it set for 12 psi. At most it will spike up to
13 psi. At 12psi on standard engine/turbo and good size exhaust
And fuel pump you should see close to 200 hp |
