Default Alignment causing pull under acceleration?

I had my car re-aligned today and it seems to drive pretty straight but when I get on the gas with the car in a straight line and the wheel pointed straight it starts to pull either way fairly quickly. Prior to the alignment it did not do this, however the wheel was very slightly off center but would still track straight. The new specs are as follows:

Front camber= -1.7 both sides
Toe= Don't remember exactly but very slight toe in equal both sides
Caster= Around 5.4

Rear camber= -2.3 both sides
Toe= .40 total toe in (.20 per side, UK alignment settings)

Any opinions or ideas on how to fix this pull are much appreciated.

Check tire pressure. Make sure they torqued all of the alignment bolts correctly... I have a problem with this recently.

^Tire pressure for sure. Even a 1psi difference will make it pull...3 PSI and on wet ground, going straight, if you punch it, as it hits Vtec the car will go sideways....ask me how I know ;[

Thanks guys was tire pressure. Left rear was at 28 psi, right rear was 35 psi off by 7 psi! Seemed to fix the problem once I evened everything out to 32.

^Lucky you caught it and noticd it during the dry times.. on wet, with a 7psi difference if you hit Vtec your car will NOT be controllable. Mine with 3psi went sideways and if you let off too fast itll kick back the other way...I was basically sideways for half a block in 2nd gear after it hit vtec as I slowly let off the gas to control it... scary as f***
