bigger injectors.
New Maf caled for injector size.
Get the car Tuned.

If you still have the stock fuel system you may be able to band-aid it by upping your fuel pressure but without a A/F meter or logger its hard to say what to set it at.
 
You'll probably need to get it on the dyno or get a wideband to see where you are at, it's hard to say what your AFR is.

Shoot for 12.8-13.0:1 and 32-36* total spark for good power at WOT.

A custom tune is going to really help you get the most out of the car at all throttle positions and make it drive like stock again.
