Im having yet more problems with my car
It is a fiesta xr2 with complete erst running gear

Problem one - car seems to be struggling when it comes on boost and even off boost when it is running from cold you can pout your foot down and the car seems to really hold back before revs pick up. When warmed up and boosting,it doesnt seem to boost cleanly, it sort of feels like it boosting a bit fluttery like if you know what i mean?!

Problem Two, All of a sudden my car seems to be blowing the fuel hose off in the engine bay which is coming from the fuel tank. Hasnt been a problem for over a year and now all of a sudden it is going tits up. Could the fuel pressure regulator have gone tits up and not be sending it back to the tank causing massive pressure in the fuel lines and therefore the hose to blow off?

P.s. I have recntly fitted a secind hand chipped ecu to my car and this is when i started blowing the fuel line off, although that could be coincidence. It is allegedly a bbr stage three unlmiited boost chip (does such a chip exist) ive had it apart and it is deffo chipped.

Any suggestions really appreciated!

M8 wish i could help , but on what u wrote i would say the chips ur problem wa ur boosting problem ither take it out and try with ur old chip , this is what i would do to rule out some stuff and would have a quick look at ur wastgate make sure its free etc and is doing what it should be , and with the fuel lines m8 i cant help u there , hopefully sombdy on here will , hope u get it bak runnin again , coz bait it goes like fuk

 

Thanks for the reply mate! I should prob update it cos i have tried the car with a different ecu and fuel injection module and it made no difference.
Have regapped the plugs, and changed the fuel pressure regulator but not solved the problem.

im guessing at the metering head/regulator/fuel return...
if the fuel line from the tank is blowing off then might ba a blockage going back to the tank... excessive fuel pressure etc... could be overfueling causing the hesitation..
as i say im guesing but trying to think logically...
