engine not pulling as it should

[greyxr2]

Hi,
i have been reading posts for a while now and it is starting to sink in, but im not sure if my fuelling is the cause of my engine not pulling on full throttle,
I would really appreciate some feedback on my data log, just to see if i am somewhere near where i should be.

Thanks in advance

Your MAP sensor is reading a constant 100, fix that.

At full throttle and accelerating, your AFR is between high 13s to low 14s - I'd say too weak.

Thanks for the replies,

I should have said its a 2.0 zetec engine with individual throttle bodies, with no map sensor.

Do you think the whole map could do with more fuel, say 5-10% more, or just full throttle? from what ive read these engine like to run slightly rich but i could be wrong...

Cheers

That's at least six degrees more timing at full throttle than what the last Zetec we tuned wanted.

Posting the MSQ could still help.
