i converted my erst to efi quite a while ago snd its been really reliable once it was setup,i was out in the car earlier and was having a couple of problems under acceleration,to start off with i thought it was were i had gone over a bump and my foot had lifted the throttle a bit and caused the turbo to chirp as though i was changing gear

i got onto a piece of dual carriage way near me on my way home and started accelerating and it did it again but i thought it was from going over a bump again,so i pushed my foot down hard in 5th and it started doing it again but this time my foot hadnt moved,does anybody know what might be causing thisatall please
