the 86-88 turbo II making 183 hp. the 550cc's open to 56% duty
and the 89-91 making 200 hp. opens to 63%...
make more power with either. and both ecus will go alot over 63%....
and for the main post on this. there is no way you should be going lean at 10psi at 5000rpm... something else is wrong with your car. my S-afc at 10psi with stock injectors and FD pump is in the negitive %. as in I leaned it out!...

at 38 psi in the rail with the 13.2 AFR with 550 cc injectors and 220whp or about 275 flywheel hp they should be either maxxed or running close to it...u cant calculate this percicely since there is not enouf data...so on the car it should be diffrent.
like i said before, his fuel pump is either not working right, is wired wrong, or his injectors are clogged, getting a fuel pressure gauge will help diagnose the problem further...

Scott 89t2- you realize the 88 T2 was under rated in the US right? I dynoed 178rwhp STOCK, 5.5 psi, and so have many other people, so that comes out to around 215 flywheel hp, which was the hp in japan's infini...

Yeah, I've noticed a big decrease in gas mileage.
Gsracer: maybe you should keep your post counting to yourself, or find a new hobby... we don't need people stating the obvious.

Thanks,

EDIT: oops, I just noticed that you were running rich, so partly-ignore the "hot air" comment

A pump and a aftermarket FPR to regulate pressure back to normal?

I'm getting 12mpg on highway estimate... I have the #'s but have not done the calculations.
I think I have the bad gas mileage record for non-ported cars
I got about 180 miles on my last tank.
and the wierd thing is... there are no funky smells coming from exhaust except for normal, no bleeding sore eyes, no smell from the engine compartment, etc etc... though it does backfire a good bit and it bumps coming off the idle.

a front mount is not going to increase your boost. However with the front mount it will be safer to run more boost as the chance for overheating the air and in return causing detonation is much lower. The stock top mount is in a pretty crappy location to begin with and over 11-12 pounds of boost it becomes really ineffective. If you have really hot air being thrown into the engine this makes detonation that much easier. You might notice a little more lag, but then some people say that a front mount had little effect on lag at all.

I'm in the mid 11's for a/f ratio at 10-11 pounds.
232 rwhp.
Still just the walbro.
