Mate it's not because you falcon has no power low down, I beleive the offender in this case is your auto transmission.
I have an ED, it's the same.
It's a known fact that falcon auto's a very tally geared. (with commodores being the opposite)
Convert to 5 spd manual, or get a an electronic shift kit. 9psi_EB makes these and sells them for peanuts, I have heard good things about them.
Good luck...

I have an EF2 ghia and i can beat every stock commy from VN-VT, off the mark. I dont know why you cant.

I think the EF2 ghia's had the xr6 motor don't they? And also different diff ratio from stock... could be wrong, but this would explain a bit..

The XR6 motoro is only an extra 10kw or something

It's not cheap, but an option would be to get a higher stall converter fitted - there are 2500rpm stall Dominators to suit the BTR LE series 4 spd trans at www.VPWmailorder.com.au - pretty sure they're about $650 for the 6 cylinder one (then shipping and installation is on top).

EFII Ghia did have XR6 motor, as well as 3.45 (same as commodore) rear diff ratio...

Diff and manual would be the way to go IMO. Depending on how good you are with cars, you can pick up a manual EA for $6-800. The box has slightly different ratios but will otherwise bolt straight in. You can keep the EF computer and fool it into thinking the auto is in neutral by running a 6.5 to 7.2 K-ohm resistor between pins 91 and 64.
A decent diff will set you back a similar figure.
Just remeber to at least double all estimates of cost if you pay somebody to do the work for you...

How about one of my TransModules,

it wont make it take off any quicker, but it will definately help the auto jump into the next gear instead of its usual smooth slide into the next gear.

Email me or see my site for details.
