Car running lean

[RobVT]

hello, i have just been on a RR day with the lads from up here and the car has a revo stage 1 remap, forge TIP, scorpion catback and a green airfilter
my results where 177bhp and 232ftlbs of torque i was wondering if my car is running down on power?
on the AFR graph it shows the fuel to be around 10.5-9 is this too lean? and what do you think could sort it out i have replaced the maf cos it shot up a code a while back, could be a dodgey remap or something causing this ?

thank you very much in advance

down seem down a bit... i would expect about 190 ...

and afr should be around 12 iirc

Doubt it will be the map because stage 1 revo is a generic map.

177bhp is a bit low should be around the 190-200 mark with the mods you have.

You have a boost gauge..?? whats it showing.

This is easy to misread and make a mistake here, but are you sure you aren't running rich.
an AFR of 10.5 :1 is richer than an AFR of say 12 :1.
When a car overfuels max bhp is not realised.

An AFR of 10.5 :1 is not good as most tune for about 12 :1

your prob loose 15-20bhp from running that rich, i did with my punto gt.
