ko3 turbo's on agu's.. how laggy/slow to spool up is yours?

[The Dave]

I didn't think APR maps were renowned for being rubbish? lol

wel something is making your turbo spool up slow an cant think of anything other than the map.. unless  sensor has gone..

+1 never heard anything bad  

Topher is the man to ask about this thread

APR maps kick like a mule low down, and a k03 should spool noticeably faster than a k04. If you're lucky it'll just be a boost leak or a faulty maf or N75. If you're unlucky it'll be cracks in the turbine housing or dead actuator.. either way i'd say its something wrong with the car rather than the map.

Let us know how you get on with this 

[The Dave]

Deffo one for Nick and the R-Tech boys to look at then. Time to get it booked in

Not sure where Topher is based, I'm about an hour from Leicester/R-Tech. Topher it doesn't kick HARD or anything, it seems very progressive all in all. Torque seems linear between 3k-5k, but thats just from my bum dyno lol

I reaalllyy hope they're open over xmas haha thats the only time I can wangle off and I've been wanting the TIP and DV for months!

[topher]

Pull the top N75 hose off (the one directly opposite to the TIP) and see if it boosts any earlier. Don't rev any higher than 4krpm and put the hose back on immediately after testing. If it boosts harder its most likely a sensor, if it boosts the same it points to a leak or turbo/actuator issues.

good advice above..

[The Dave]

I am completely unaware what I am doing under the bonnet apart from checking oil etc haha.. is it easy to get to, assuming near the recirc valve area with the pipes around there?

[topher]

yeah between the maf and dv. Little solenoid with 2 thin hoses coming off it and an electrical plug. If you follow the hose coming from the side you'll see it goes straight back to a boost hose, so don't pull that one off. The top one goes to the actuator, so removing that bypasses all ecu/N75 control of the boost leaving it to spool as hard as the actuator will allow.

edit: you can also just clamp the hose with some small mole grips, probably easier that way if its still got the one-use vw clips on.
