N75 advice (Liquid Gauge) S3

[S3orge]

Hi guys I wondered if someone could teach me a bit about N75? I have a liquid gauge installed and get a peak of 94%. I have a stage 1 s3 with milltek cat back and ITG induction. It seems to spike briefly at 94% on throttle and then it will drop off? Does this seem right/expected?

Any advice would he appreciated. Thanks
