Just had her on a rolling road, she ran 286bhp on her first run. I was getting a afr starting around 12.7 dropping to 11.5 then back upto 12.5, this is using a 3.8bar fpr and a gtec 2 hf chip, are these reuslts ok or is it worth swapping to a gtec 2 or back to a 3.0 bar regulator? there are no print outs, as the printer didnt work. i am going back tomorrow lunch for another play on it (as they didnt charge me for the runs today due to not being able to have any print outs). They will let me swap the parts about there at no extra cost

What other mods do you have? 12.7 AFR is too lean I would have thought, if that's on boost. 12.7 off boost is too rich. Maybe you'd benefit from a live map?

12.5 at the top end is too lean IMO - bye bye pistons.
Did they check the car for detonation?
Going back to a 3 bar reg or the leaner chip will make it worse. What is the spec of the car and do you have an uprated fuel pump?

They didnt check the car for detonation.. I have an uprated fuel pump in the garage i cant get the cap off the fuel tank to install it, no matter what i use its just stuck, might have another bash at it tonight. it does have the wiring mod though. Spec: GTiR hybrid, Pro alloy FMIC, Apexi filter & tapered sip, Gtec 2 hf, 3.8bar fpr, decat & ss exhaust

Get the uprated fuel pump on and try again. I think you might have to take the swirl pot out to fit it. If they cant check it for det then take it somewhere that can

put a 0.8 bar actuator on and it should do if your boost controller is set up right on your setup.
Checking for detonation is very important. As you are running lean I bet your car is. I would seriously not push your car beyond 5,000 rpm until this is sorted.
I would also put money on your running lean at the top end due to the fuel pump not being able to supply the fuel - this mod should have come before raising the fuel pressure IMO. The standard pump usually maxes out at 270 bhp or so. You have to remove the swirl pot to fit a walbro 255 and also modify the pump housing.

i dont think that i have the boost controller setup properly in that case, as is has a 0.8bar actuator on.
i best ease off on the old gogo pedal....
looks like thats my weekend planned, doing the fuel pump...

You dont have to drop the fuel tank - it will fit through the hole in the boot without it. It's fiddly to do, but possible.

i changed the coop pump onto my marea last night, only took about 30 minutes so you should be alright, the plastic screw ring is pretty solid so just give it a good battering Ry

Think about it this way - how many rolling road runs do you want to pay for, including messing about with different chips etc. until you get it a right as possible?

obd? on board diagnostic? If so, it's a little plug just in front of the coolant tank.
