General Is this running normal?

[Vincent Pandolph]

Hey guys I have a 1990 Eagle Talon TSI AWD stock engine, 100k on it. I have upgraded downpipe 3", cat delete tapers off to a 2.5" HKS HP cat back, K&N drop in filter in u chopped can, Walbro 255, -6 fuel lines throughout, Weldon pump racing filter, Fuel Lab AFPR, AEM WB.

I'm testing it out since I only got it running 800 miles ago after it sat for 19 years outside. I also have a Jmfabrication fuel cell.

At cold start after WB heat cycle, it reads high 12-13.5 and rises to 14.7ish as it warms up. Cruising in any gear runs close to 14.7, as it's constantly fluctuating while the ECU and O2 sensor talk. WOT I'm seeing 9# boost and AFR as low as 9.2 at roughly 6k rpm.

Does this sound like I'm doing it right? Only leak I'm aware of are some small cracks in exhaust manifold indicated by white exhaust stains, but you can't hear it leaking. I have an OEM style exhaust manifold for it.

Waiting until I change head gasket to finish what I want to do with it.

Sounds normal to me.

Sounds normal with the parts that you have on the car. 14.7 is stoich or the right A/F ratio when cruising and idling. 9.2 is running way rich on fuel so you need to either turn the boost up some or have a way to tune the car with the aftermarket parts that are on it.

Stock ecu targets 9s afr in boost. Everything you mentioned is normal for stock ecu.
