Give it a week, might take the car sometime to respond to the change.

Tried resetting the ECU ?

If the car feels sluggish, the first places I would look is at the fuel trims (LTFT) and check that they are not more than +/- 10% as well as boost levels at WOT - these should spike to ~17psi, hold a good 15-16 and then taper to 13-12 by redline on a standard car with a SRI.
The car should feel faster - not slower however.
What tools do you guys use to monitor the engine parameters in Australia? We have several devices - one of the most popular is the MSD Dashhawk.

Hey Guys
Thankfully the car feels good now.
Out of curiosity, how do you reset the ECU?
Thanks to all that have helped.

Disconnect your battery, press brake pedal, give it a few mins then re-connect. Drive for about 40 miles, mostly town/city driving if possible to learn the fuel trims. Just going for a drive at 70mph is not 'best'. Up through the gears, gentle driving without going WOT would be best in my opinion

huh ? why would pressing the brake pedal influence the ecu when the battery is disconnected? for give my ingnorance here.

Gets rid of the residual power in the electrical system, easiest and safest way to do it. When the brake lights don't shine all the power is gone.
