2013 Vauxhall Astra Energy 1.4 --- gutless!!

[Tim M DB7V]

I recently changed my 2007 Astra Energy for a 2013 Astra Energy, what a disappointment!!
The 2007 car was fun to drive with good performance for a 1.4 run of the mill car, even with over 100,000 on the clock it went really well.
The 2013 car is hopeless below 3000 rpm, no way can you drive from a junction in 2nd gear and trying to accelerate in 4th is embarrassing!!
I was wondering if the 17" wheels have anything to do with this (the 07 car had 16"), have they left the transmission (ratios on diff & gears) the same for the 17" wheels resulting in the gearing being too long.
I was wondering if getting the car chipped for more torque might help.
Advice and comments gratefully received.

It does on this, they are not low profile tyres.

Disappointing to find a 'troll' on here! The 16" wheel has a 205/55 16 and the 17" has a 215/50 17 which gives about 2cm greater diameter.

Sorry I think spell checker has altered your question!

The 2013 Astra weighs 367Kg more than the 2007 version!
I think you may have solved the problem Mr E.

The 2013 car has 10 more bhp which obviously is not enough!!

Thanks guys.
I'll just live with it I guess.
