Hey dude, I put a hks actuator on and looped the hi lo and checked for leaks. I've just tightened the belt some more and reset the jam pnp.still feels like I hit a brick wall between 4 and 5k rpm, it has new plugs leads and dizzy so can't work out what it is. I might try the stock ecu to see if it's the jam pnp. I also have a rrfpr on the car that was on before I got the car, i don't know how to adjust as never used one, as the turbo is a bit bigger then the stock one, will I need to adjust the rrfpr?. I'm thinking It might not be fuelled properly. I got the jam so I don't have to play around
