The chip is set up with that fuel pressure so leave it alone and adjust everything via a Translator.
Especially with alky, the translator works great because you can easily pull WOT pulse width by 2% increments. I pulled 10% of the 60lbers at WOT in the Translator with my alky kit knob at 2 oclock and was right on 800 millivolts before it blew up.

Fuel pressure is to be set for drivability issues. WOT is then set via chip programming and adjustments to the translator to get your target O2's/Air Fuel Ratio setup.
Its all bout tuning.. you need to see what makes the most MPH pickup from the 1/8-1/4 and then use that info on your particular combo. Typically safe numbers to shoot for on a street tune is approx 800 for O2's. This will vary from car to car. Track settings typically 770's as a baseline at WOT through the last half of the track(past the 1/8).

Those settings are correct. Why did something let go? That is the question...
Did you have a datalog like a DS recording of when it happened?
Sorry to hear about it
The more heat you place on the O2 sensor the lower it will read. It takes time to get the heat up.. I would say you'd be very close on an 1/8 mile tuneup through the traps.
Thing is with 1/8 mile we can get more greedy on the tuneup.. since there is less track :biggrin: . Watch your MPH in relation to timing, boost, and O2 levels. If you get knock.. and the O2's are a little high.. you need more alky shot in and back down on the gas. Vice versa, having the O2's a little low and get a little knock.. try adding fuel and leave the alky alone. Dont try and use alky as the fix all bandaid.
