Car Running To Lean

[Gtr Glafche]

Hi guys,

Just a question regarding my car running to lean, what should i do to get it to normal stage and am in danger if i dont fix this problem.

How do you know if its running lean?

It will ultimately lead to detonation and cause damage I.E melt a piston for instance.

If its running lean I would be tip-toeing it to my tuner/mechanic. There will be a reason its running lean (faulty fuel system diagnosis, poor tune, etc)

Well it just came off the dyna, Computer is fine, and everything else is perfect, nothing showed onhe computer or the dyno, so im sorta scratching my head.

Could it have something to do with the airflow meter.

Thnkx for your input.

If it's been on the dyno them post up the dyno graph for us.

What air/fuel ratios is it running?

Unfortunately cant post it up as i dont have a scanner currently, so if it helps i will just write down the details below the graph, dont know if its correct, if not, just let me know what to look for, thankx.

hi guys, im just organising the graph, and im in the process of having to change my airflow meters, cause i dont know if any1 else has the problem of the car cutiing out (not turning off) just a jolt etc. It only happens 0-2400rpm, whenever boost kicks in its ok, never have a problem.
