Since doing the air box mod ( removing the resonator ) The car is hitting fuel cut or overboost due to what ??
at around 3500 - 4000rpm its peeking 1.18 on the blitz boost controller
Before doing this mod you could easily peak 1.25 - 1.30 without any probs.
Is this due to the ecu and why now ??
Lambda is showing a little rich low down and knocklink activity has gone up to a first green...
Fuel preesure when hot is 3.2 at atmos and 2.6 with vacumn..
Any ideas guys at what sort of set up i should be looking at ????
