Hola fellow motorRs,
just registered and this be my first post~
and i have a question on loss of MPG after unichip.

List of Mods i did on my Mini

2005 MCS (6SPD)
1) CAI
2) Alta 3" cat back
3) 16% M7 Pulley
(and under the hood Mini eyes)

and finally last week i got my Unichip from M-mania, i installed UniChip and fill up my gas tank full (91 Oct), reset my Odo Trip to Zero
and now it's almost time for refill (1-1/2 slots to go b4 empty, Chrono Pkg)

My Trip is now reading 255miles and before Unichip I would be close to 300 miles already.(normally i get about 350ish+ miles/full tank B4 Unichip)
Losing 50++ Miles/full tank? so is this normal? if issue was previously covered
kindly disregard my newbie Question.

Good day all
