As well as having your fuel pressure cocked up, your SD will be done wrong too.
You need an AIT sensor in the manifold.
Otherwise the tune drifts with the change in weather.

OP, did you ever try a new or known good MAP sensor?

For those who haven't yet figured it out......
SD means speed density.
The density part of it means air density IN the intake manifold.
That is measured using a MAP sensor for the pressure part of it.
It is measured with an IAT sensor for the temperature part of it.
Air pressure IN the manifold and air temperature IN the manifold make density IN the manifold.
Fuel temp will never work accurately because fuel temperature is not air temperature.
In which case it isn't an SD tune it's a SP(speed pressure) tune which nobody uses because it doesn't work accurately enough.
If you're not worried about accuracy then just stick a carburettor on it.
Maybe mr wannagetitdone should stop posting bull**** information?
edit......you need a new toooooner too.
Fancy suggesting you need a new battery?

So you don't agree on the definition of "speed density" then?
You're a "tooner " too?
That's right....you've been toooning for 20 years and using a WB for 20 years but they've only been on the market a bit over 15 years.
This man knows a bit.
Just a bit.
Reverting to a MAF tune will fix most of it.
Not all of it.
