John post what you have in your 87, inj,turbo,chip, etc etc etc
mods are as follows:
40 lb injectors, PT51 Turbo, caspers thumbwheel chip burned for 40 lb injectors, switch pitch 400 tranny with 1400 low stall/4000 high stall, ported heads, .030 over TRW's, 3 inch downpipe, a conley peformance plus upper plenum, scanmaster 2.0 scantool.
I have FP at about 37-38 PSI and it reads on the scanmaster 850ish for O2 millivolts. My understanding that this a bit rich? It was at 42-43 FP before and the O2 was at high 800 low 900 but I thought the there would be a bigger diff in O2 volts going from 43 PSI FP to 37 PSI FP. Boost is at 14 PSI. Let me know if there is any other info needed.

How fast are you now?
May consider a new chip, or send in you thumbwheel for an update!
With the high stall you have you can go with a much bigger turbo as well, but injectors would follow....
Plus a little race gas and TURN UP THE BOOST would make a HUGE difference!

went to the track before it closed and I ran a 15.xxx, cant remember exactly, or maybe I dont want to remember those horrible times. That was with the stock turbo on pump gas at 14 boost though. I am aware that the stall is way high, I am currently debating whether to change the stall or go back to a 2004R, the commute to work is like 30 miles and the o-drive would be nice.

John put some bullets in the Tank (ie C16, Zylene) and Crank up the Boost but ENSURE you have more octane do not want to make Milkshake in the OIL .....Blown Head Gasket....Not really any sense since their is no Track anymore to Test and Tune, and If you are Racing on the STREET'S BE CAREFUL I know its kinda hard when a rustang pulls up next to you, and rev his motor, but they are NOT WORTH your GAS or the possibility of Grandma is crossing the street in front of you.....Ok I will get off my Soap Box now.....WE NEED A RACETRACK LINDA & MUFI hook it up.....
