Technical More from (ace) GSR induction kit?

[Alex22]

I had a GSR F1i kit fitted at the weekend at brooklands> and its amazing! BUT i seem to have lost around 3mph at the top end (oh big deal!!!) any way i could combat that??

Cheers guys

adjust fueling by getting it mapped

You sure the 3mph couldn't be from different weather, wind and road conditions?

I don't think so> it used to sit at 110mph (indicated) nicely whatever the weather/wind> now it struggles to hit that speed.
