Usually talaga, pag nagpapalagay ng indiglo, mejo magagalaw yung mga needles. I just had mine installed 2 weeks ago, tapos nung binalik yung gauge, yung sa fuel indicator ko, lower than when I had it changed. Pero, when I topped up my tank, umakyat naman, and its been acting normally.

Try to top up, then observe the needle. Pag hindi tama yung reading, then nagalaw ng sobra yung needle, at nawala sa calibration, kasi nga sensitive yan sa pressure. Sa casa, they can try to re-install and re-calibrate your gauge.
