Help!!!! ASAP

I've had larger injectors put in and uprated chip to support those injectors. Anyway once they had been put into the engine drove great on they way home but kept it below 2k revs for a 5 mile journey because I didn't want to do any damage to the engine bore wash etc. I then went and changed the chip out from the socket ecu which I had in the car and now runs like sh*t? Lumpy won't idle and cuts out? I at my last patients with it and looking for help ASAP :( I'll attach a video

    You've been a bit unclear there.

    You did 5 miles without the uprated chip?

    Or

    You changed the chip and the injectors, drove 5 miles, then changed the chip again?

    Since he's not online... Hes got some 555 injectors, had them put in at a garage and drove home. I believe he then changed the chip to a one that's for a suitable map to run then.

    My bets are on the ecu connection..provided all the injectors and their connectors are sound.

    You're welcome mate, glad I could find the issue. Like I said, get the MAF and filter dried out. If that don't work, you'll need a new MAF
