Right I looked a the tables and can't understand what you are saying. Can you give us an eg at what rpm you are referring to (I see the kpa) and what the value is (in the table) and what it should/needed to be and what the impact of the current value versus the new value will be. And here is me thinking the bloody needle and seat was a drama- not by the look of that stuff!
'68 J-code GT Fastback
'67 S-code GT coupe, 'Pink Bitz' formerly known as 'Hookin' up a brother'
'69 M_____ GTS Fastback 'Blasted'
Ha ha, mate its a brain twister but like anything the more you stare at it the more it makes sense. If you see the kpa, it starts at -100, which is -14.7 psi. At 0kpa, it is 0psi, essentially full throttle in an NA motor. After that it is in boost. I thought that 100kpa was 0 psi, and tuned accordingly. I thought boost started at 200kpa.
Normal atmospherics is 14.7 psi, or 100kpa. So I thought that boost started from 100kpa, and 0kpa would be vacuum. But Haltech uses -100kpa, which is full vacuum, and 0kpa is atmospherics.
Its my bad, i didnt look at it properly.

Yup. Not big time as i did the tables very conservative, but still lean. I was more worried about my timing though. Gt40p heads dont like timing under boost. I was at 26, again not too bad, but more thsn i wanted. All good though, fixed it now.
Got some new rear tires. Hankook RS3s. I only bought 2 for the rear as I wanted to make sure they fit due to them measuring wider than a normal 235. They just clear the guard on the rear as they are 'half rolled'. Might roll the lip fully soon. St George Tyres have a sale at $150 each, which is bloody cheap for RS3s. I will grab another set for the front soon

Cheers fellas. I added an electronic fuel pressure gauge and an afr wide band gauge, which is connected to the left bank. The haltech is connected to the right bank and adjusts only off that. But at least I can monitor both banks now
Yeah the haltech does too, but the voltage output isn't configurable, so won't work with the gauge I have. The tech edge one I already had is configurable, so I just kept that. But at least I can watch both banks, might be useful for trouble shooting in the future
