Any updates on this, I have pretty much the same problem. my car wont even run unless I richen up the mixture for idle ALOT. I noticed you had to do the same. I dont have a problem doing that but it doesnt seem right. It seems like something is wrong. My specs. 87 mk3 running maftpro in speed...

Yes the IAC is just open to Atmosphere

Wow I feel stupid, thank you for pointing this out. There is not a whole lot worse than sitting here trying to find a problem I dont have. It is in Psi which is just about perfect vacuum. So now the issue is why am I running lean at idle?

If it is not supposed to idle at stoich then what is it supposed to idle at? and what is a safe AFR range for idle?

Power output seems good to me, but Im taking it easy because of the rebuild. It was an NA car before and I have never driven a stock turbo supra but it feels stronger than it did NA.

rebuild only has about 150 miles but -9.6 is really low vacuum and I am also running lean at idle if I dont add a lot of fuel on the maft-pro which again supports a vacuum leak but I cant figure out where else to check. And the map sensor line is short and silicone and directly off the port in...

I assume it is inches HG I found this link http://www.cygnusx1.net/supra/TechTips/vacuum_gauge_readings.aspx This shows that it should be between 17-21 at idle. It gives a lot of possibilities on what it could be. It really seems like a vacuum leak but I got no response from the brake cleaner.

Hey all, I have recently installed my rebuilt 7mgte and am having to add a lot of fuel to make it idle at 14.7, I have good fuel pressure. What I am noticing is that my vacuum is at -9.6 at idle according to my maft-pro. It should be about -20. I am thinking vacuum leak but have sprayed...

So to sum it up I should do both as they are both going to be necessary for this build. As far as I can tell there are no other components in the system that would create the need to add fuel with larger injectors.

Would you suspect the pump before the fpr? Is the aeromotive kit worth it for my application?

Yes stock pump for now, I have a walbro to go in it but I didn't think that would cause this considering it has the issue at idle as well so the pump should be sufficient

I just installed my rebuilt 7mgte 60-1 trim ct-26 with 550cc injectors and maftpro running in speed density, the issue is that when the mainscale is set at -25 like it should be for 550cc injectors it runs lean, I had to set it for over +20 to make it run good. It runs good at that setting...
