Lean running

[Jon441cc]

Just a little query for the guru's, i recently had my car dyno'd and the results showed lean running which i think is the fuel filter restricting fuel flow and the high output turbo i fitted, but the dyno gragh only shows 12psi peak boost pressure, would lean running make the ecu limit boost pressure if the lambda shows lean running.

How much boost is it mapped for?

The car hasn't been mapped yet as far as i know.

Your new turbo will be flowing more air than a K24, without a remap you wont be getting the best from it. Be careful you dont burn any valves etc.
How big is the turbo? bigger than RS2?

Standard S2 is set for 0.8 bar of normal boost which isn't too far away from 12psi. Overboost will give 1 bar (14psi). Get a custom remap as you may will more than likely have high exhaust temp from lean running. Not recommended! And you'll get more power as it'll fuel better. Bonus!

K26/T04E Highout Output

Wow that thing really is the daddy.

Jon, I think you need to go visit Mihnea...

I cant wait to have the car remapped, then il see some real power But the next job on the list is to replace the fuel filter as looks like it has never been changed

12psi is 12psi nomatter what turbo you use (same amount of air into engine)
