Super easy to check by checking header temperature on each cylinder after a pull. Something is for sure off.Gas smell? That's not right. Are you sure all your pistons are firing?
I don't know if it's timing or the cylinders - my shop inspected the cams & timing & confirmed it was correct. Also, I only smell gas when the engine is off, and it's coming from near the surge tank, not the engine. It's at a level where you need to be sniffing around there to smell it, but parked for a day it starts to stink up my small garage.The more I think about it, the more mysterious this becomes. With the AFRs looking so good, it must mean that all cylinders are firing. I can think of only two things to cause low numbers:
- very retarded timing
- some sort of boost leak/low boost issue
I am not sure where the gauge reads but it is slightly confusing. What you actually care about it the pressure delta at the fuel injector. On a NA car, 43psi all the time is good. On a forced induction car you care about the delta at the fuel injector. Fuel pressure in the rail should increase with boost pressure.I do have a BOE fuel pressure regulator and pressure gauge coming off the surge tank on the fuel line. According to my shop they did look at this value and it appeared constant during the dyno run. I'd like to verify this myself so I'll be installing AFR and fuel pressure gauges soon. The one in there is a little inconvenient, being in the engine bay. If I'm understanding you correctly I should see that number stay at 43.5 at WOT at all rpms.
