I finally pulled the trigger in May and picked up a WE4 with 50,000 miles. The car was all original with the exception of a new fuel tank and stock replacement pump. I replaced the turbo (bad seals), rear main, did the brakes, new aluminum radiator and a host of other maintenance items.
I just put in 60's and a tt street chip. I also did a new 255 fp, hotwire, bosch 237 reg, new plugs & wires. I'm getting a few degrees of knock occasionally at light throttle cruising around town. At full throttle O2's are upper 600's to low 700's with a couple degrees of knock. BLM's are consistent 124-134 range, usually 128. IAC's are slightly high at 45 and TPS is in range. The chip was burned for 16-18psi and my boost gauge is showing 10-12 (keeping it low for now). There should be plenty of fuel at that boost level.
On my TTA (12,000 miles) the O2 readings are 820-840 at 20psi with alky (zero knock). Also, the cross counts increase much faster than in the Buick. Flaky O2 sensor?
Thanks!
