New to me Orange XJ DD
Can't wait for videos!
You could use a dyno..they have those tail sniffers that read like a wideband...just make sure you tell them you want it a tad richer than they think is good because its bette rto be a little safer, than sorry!
And that only works if you don't have a cat...

nope its my DD, guy before me took the cat off. its running good, but just feels really really rich, this tuning thing is getting frustrating, specially since i drive it everyday, guess thats what i get for turboing it!

Good thing with those AW4 is they are the same trans in the TT supras. They used a 4 speed auto in some as well!
So theres some upgrades that can be done to get some higher line pressure/quicker shifts! Also some stronger clutches incase you ever rebuild it!
Get a trans cooler & flush that trans..its going through hell right now!
I'd look into draining & refill as well! Possibly check the trans mount see if its broken..
I'd use nothing less than Redline MT90!

it sounds like something in the trans is rattling once i step on it, like a pebble or something is bouncing around-that sound. ill try draining it and flushing it! so which one, an apexi afc or split sec psc1001? or apexi older 5 **** afc cause they cheaper? anyone got any of these to sell? lol
Apexi Neo I think is what its called..its the newer version of the SafcII and control the fuel more precisely...I think 16 points per 1000rpm vs 12 of the SafcII.
And then you need a wide band! AEM uego. My guess it that when you drain it, you'll probably find out whats rattling..I'm concerned maybe its a tooth off on of the gears or something...
