i have a h22a in a hatch. i am runnig an automatica p-28. now if i get it chipped p-28 is that a big differance for the better?

 

yes

BTW, awesome time in your sig!

Are you gutted?

 

defiantly a big difference, fuel maps, ignition are all for a 1.6l sohc, rev limit is much lower as well.

I offer few programs which are based on the GSR/P13 ECU they should transfor the powerband. check my sig or PM me.
