Strange up/down boost problem

[-=Rob=-]

Cool - Thats good news, I don't often give it much beans but just in case I'll be leaving it at 2.25deg added. Ollie as always you've been a great help, muchly appreciated

all due respect - bollox.. the map would have been fine when it left me and will still be now. Maps dont change

Check your pipes for leaks etc etc.. map is not the cause, it did'nt do it when remapped, so "something else" has "changed" - look there first. Whats changed since?

No remap will map out an inherant fault.. you will waste your money
Sounds like you have some pipe issues and some bodged solenoid bypasses done on there... all of which can piss the ecu off and cause running problems.

If you want it looking at, call me...

Sorry i had been told that due to me unplugging the ECU all the time to reset it, there is a good chance it could mess the map up? your talking to a chap that doesn't know much about turbo cars and mapping here!

mine has now changed. now running a 007p and a new N75 (£66!!!), unplugged MAF and throttle response is better, but still giving me grief:

foot flat to the floor any gear, idle-4k = 10/12 PSI, @ 4k EXACTLY, shoots up to 15psi, then @ 5.5k drops to 5psi.

will be bypassing N275 tomorrow (looks dead easy, already have vacum hose) (using this: http://www.vagowners.co.uk/forums/showthread.php?t=303 )

any other ideas?

car is physically chipped, no idea who by, only know this because motec had a look for me yesterday and it was encrypted...

no fault codes on VagCom.
