On going customer project.
1998 Golf Mk4 GTi AGU
AGU k03s
Forge Actuator with yellow spring and N75 C
Forge FMIC & TIP (stock MAF)
Turbo Back Exhaust System
Stock 3 bar fuel system
Calibra Turbo C20LET 306cc Yellow Bosch injectors
Live custom dyno remap with simulated development ecu, PWM logging, twin lambda probes and rail pressure logging to setup a fuel map to run the AGU stock MAF with the Calibra yellow injectors with a flow rate of 306cc @3bar.
Just running the injectors with no mapping made the car run 200bhp, 20bhp less than the oem injectors, reason being was the fuel was far too rich across the whole rpm, the enrichment fuel dump was off the scale below 9:1 air fuel.
As far as I know this is the best fuel and power result so far from using thr Yellow top injectors..

Final mapping result today was safe lambda across the whole rpm range of 11:1 and 238bhp 268lbft....

A few more hours on the dyno mapping will allow us to dial in the perfect fuel and timing maps.
SO far I am over the moon with the result..
