Hi there chaps.
Looking at going for a stage 2 map with you  soon hand have been trying to find out if geting one of these is worth it at all.
In you experiance is it a good thing or not. Will it help in any way?
I have seen some one selling one for good money and tempted if you say Yes it nice to have.
The mods will be for a AGU engine in a mK4

Pipercross panel filter
Forge spit R valve
K03s turbo
TIP
FMIC
De-cat
Miltek R32 system

So do you think that this is a good addtion to the list of other mods or is its a wast of time chaps?

IMO stick with the 3bar,  so far I have not seen any benfit froma 4bar reg ran with stock injectors.   The 3bar and 4bar will scale under load to around 5.5 - 6bar, the 4bar will be richer down low which is not really needed as the gain best torque fuel you need a lambda of 13.4:1 which the 3bar can do fine.

At the top end the 3 and 4 bar are the same, a pump with a greater LPH with be a bigger benefit and allow for a richer cooler top end mix,
