hey guys this is my first post on here i'd just like to say HI! and then HELP!
I've just had a new milltek stainless exhaust fitted to my B5 A4 avant TDi 110, it also has a tuning box and inducton kit,
but without my exhaust it would rocket up to 130mph no probs but since the exhaust has been fitted and when i have my foot to the floor in 4th/5th it seems like the boost from the turbo is cutting out like the wastegate has been opened.
the will just stop accelerating at about 105/110mph when my foot is on the floor.

could this be to do with the MAF sensor or do you reckon its some thing else?
i found out that my boost pressure has risen from 16psi now too 18psi will the ecu be thinking its over boosting? because of the high flow exhaust?
i'm getting a decat pipe aswell next week would that do anything?

Its really puzzling me!
cheers
Si

the decat pipe should remove a lot of the restriction and increase the top speed back up to the 130 mark poss more. you may find the back pressure in the new exhaust is not enough or too much that causes the loss of power.

let me know how you get on...
