negative deviation map related

[adsbluecupra]

i am now thinking my charge pressure control negative deviation in 4th 5th gears under prolonged load could be map related, think map is requesting to much boost .
Have checked everything vac lines,maf,new n75,and all boost hoses.
its getting a bit annoying now the car goes well in 1st 2nd 3rd but 4th 5th when flat out just hits limp mode . its celtic tunning own software currently running

ko3s
3inch blueflame downpipe-sportcat
scorpion cat back
uni front mount
forge split r
4 bar fpr
golf mk4 cai
forge tip
n249 bypass

Remember reading someone else having same probs said 4 bar fpr an map tweek sorted it

Any logs?

also i noticed your running a forge TIP... are you sure its not collapsing under full load ?

it sounds mighty like its sucking the pipe shut as its not being able not suck enough air in

The reason you upgrade to a Forge item is because the std item collapses... the forge TIP doesnt collapse.

cant do proper logs as i got a vag 5053 ebay jobbie dont think theres any way of recording logs with it . i did manage to read maf when under full load in 4th 171gs before limp mode

You need to log it otherwise its just finger in the wind jobbie.

Its that vent in the bonnet sucking to much air in.
