Thank you guys.
I've just recently had the following parts fitted;
Jperformance FMIC
Jperformance full exhaust system
Tial f38 wastegate kit
Mild steel Ram style manifold with screamer pipe and external w/g set up
Mild steel screamer downpipe (Screamer had to be blocked as it wasnt needed)
HKS fuel cut defender
SARD fuel pressure regulator with gauge
Walbro 255lph fuel pump
TRD thermostat
Air filter (Wanted this relocated - due to insufficient room the tuner just put a MESH on the turbo)
Autometer boost gauge (Fitted - lights up but shows no boost reading as though it dont work)
Car was set up on a dyno dynamics machine - made 158.9bhp to the flywheel
Now the issues im currently facing are; 1) Very poor fuel economy - £10 - 40 miles
2) After a little drive the cars idling up and down between 500rpm-1300rpm
3) Loud breathing noise from the front (im guessing thats because theres no air filter)
I dont want to upgrade turbo's or anything because my ct9 and engine are in good nick - i simply want the best set up i can get with my ct9.
Looking for power along the lines of 200bhp - I basically need a stage by stage layout of what i should do next..
All advice welcome - Thanks
