Ba Falcon Surge Of Power

Hi guys,

Have a bit of a weird issue with my falcon.

Occasionally when I got to take off, its like I have no power at all. At first I thought it was throttle related, and since the car is 10 years old, I decided to change the throttle body, tps and accelerator pedal box. This didn't fix the problem but now I have piece of mind that this shouldn't be an issue.

Im starting to think that it might be tune related?

When I first got the car tuned, I had 660cc injectors that turned out to be dodgy and caused excessive fuel consumption.

So a few weeks later I took the car back to where it was tuned and got some bosch 42lb injectors installed and fitted.

Could this changed have caused an issue with the tune? In which case I should get the car retuned?

Before being tuned I used to average 14l/100. But now after the tune I can't get it below 18l/100.

Anyone had an issue like this before? Or have any suggestions?

Thanks
