Got my car back on a dyno after Jerry reflashed it.

The car made more power and torque (410rwhp, 540 rwtq on a Mustang), but is still running really rich. AFRs are down in the 9s again as the engine gets up to speed. I then went and bought a logger from Autozone and watched IATs. Ambient temperature was 90. Low RPM IATs were ~115. Pushing her in 3rd, I got hit an IAT of 185 at the top of the gear. This probably explains why I went rich as this was a really high reading. The car did, however, get back to IATs ~115 when I let off and coasted, which tells me the IC pump probably still works.

Any ideas on what it could be?

Air in the system or bad pump. Your HP numbers are going to suffer due to the high IATs.

Is your system split?

No split cooling on the car. Think I need that for my mods? What's a split cooling setup cost?

Good idea to split the system since you have a FM HE..You need a small reservoir (BMW PS res) take it to an Indy MB tech. I'd say anywhere from 150/250 depending on the shop.

Tbal thread gives you an idea of whats needed

splitting the system only costs like $30-40 in random parts.

The IAT is tracking very high.

Mine was topping 200 F until I replaced the pump and now it stays much lower and recovers very quickly after a run.

I did the EC stage 3 with the 550cc injectors. My car also ran very rich afterward, much richer than 9:1. Been working with Jerry for a good bit after that and he came up with a cal that is much better. Runs around 11:1 and toward the top of 4th it will richen to about 10.5:1 at 160 MPH and pulls very strong.

You should call him and ask to try the "Gadget" cal.

Do make sure you check it with a wideband out on the road. I found mine to be a bit erratic, sometimes as expected and others super lean. I have replaced the MAP sensors and things are now much more consistent, but do check it over a period of time to verify things are where they should be.

I am working through some other issues now when I have the time to devote to it, but the car is a strong runner for sure.
