yeah, exactly, i'm shifting according to the boost gauge, not the tach wastegates are over rated, my right foot is my wastegate :P it doesn't really spool up in 1st, i've had it up to about 6k rpms and only 1 psi, but as soon as i shift to second, it's at about 3 psi's then i just let off the gas and get out of boost, i'm in 5th gear at about 40 mph just to stay out of boost, this ******'s gonna spool up nice though! i'm glad i went with the .63/.60

3psi from that 60-trim is prob. like 5psi-6psi from a T-25, RBwhatever, or other small turbos.

I hear if you un-hook the temp. sensor it will make the car run a little richer.. But that's "what I heard".

BTW as you know A/F gauges are almost totally useless. My A/F guage reads SUPER SUPER LEAN 24/7, but my plugs, and exhuast ports are blacker than all my neibors.

I have been running for a week with no fuel management: I have check valves on the map,colder spark plugs, intercooler,back down the timing, and running 93. I set the wastegate at 4 psi and I have not heard any pinging or (Subaru sound). My turbo is a 12a from a Starion. I took out the spark plugs and they were barely white running lean but running lean makes more power. I am just waiting for my fuel injector clips but as long as you don't up the psi I think you will be fine. The Y8 is holding strong.

Yeah, if you unhook your temp sensor you'll run rich because the ECU thinks the engine is never warm.

yeah, it's unhooked anyways cause mine goes in my intake pipe and i haven't drilled a hole to mount it yet.....

i think he means the coolent temp sensor

Not your "Intake temp sensor" your coolant temp sensor, which is located in the side of the head underneith the distributor. Also you dont simply "unplug it" because what would happen? it would throw a CEL and it would freak out, and it would go to some werid base value and wont do what you want. So what you do is.. Unplug it, (find another coolant temp sensor, d-series/b-series anything you got laying around off a core motor) then plug it in to that, and let the ****** dangle in your engine bay, so the circuit is completed and its reading whatever temp is in your engine bay, which is about 100 degrees or so. This will trick the ecu to thinking your always cold, the idle will bounce around a little bit. But this is good for 5psi, this is exactly what greddys "Black box of lies" does for Fuel management. Very HMTish.. but works

Good luck, and even if you dont do it, 3psi wont kill it, and if your really really parinoid, just unclip the internal wastegate clip and pull of the wastegate actuator rod, the flapper will stay open and wont boost at all.

Well I pretty much can't top that last post.

You could always stick a resistor on your o2 sensor feed wire that would trick it to running super lean.

sweet, it just so happens i have a blown b18 i can take it out of, i'll get on that today after work, i thought they were talking about the iat sensor, which is also dangling anyways as far as the wg trick, i have no wastegate at all, as in my down pipe has a block off plate for an external wastegate, but my external wastegate isn't hear yet, so my right foot is my waste gate yeah, i pulled my plugs last night and they were a little light, not too bad but not as dark as i was hoping. i drove to work this morning and stayed out of boost completely, i'll get some new plugs and do the temp sensor trick and do a couple pulls at 3-5 psi and see how the plugs look then.

If that's the case with the temp sensor, couldn't you throw a potentiometer in it's place with the same values as the sensor and adjust accordingly? I think i'm gonna hafta try that and let ya guys know
