Advise on coils please

Hi all,
can anyone help me out please I have an sp2 2004 its been running rough at low revs and occasionally cuts out when pulling away form the lights, I have changed the ECU not that, I hardly use it due to the bad running, however decided to get her back on the road and got an mot on her it had the baffles in the scorpion cans and the power commander 3 was connected up ran ok but still stuttered on low revs.
Anyway I took the baffles out of the cans and disconnected the PC 3 she didn't pull as well as you would expect but the bike was popping through the cans like I have never heard on a bike before this only happened when I closed the throttle off.

So im guessing that the popping is caused by unburnt gases ?
can anyone give me some ideas on how to fix this bike PLEASE.
I am just about to fit a complete set of throttle bodies which should eliminate the TPS and all injectors.
A friend has loaned me the silver box ignitor box I think and 2 coils these are of the earlier sp1 does anyone know if they are the same as the sp2 ones ?

Any other suggestions please let me know, I love the bike but its doing my head in.

Kind regards Phill UK

Go here to see if the PAIR mod has been done to your bike.

As for poor running, have you checked the Fuel Pressure Regulator? Usually you will smell raw fuel fumes when the FPR fails. Its an easy check, jondog9 has a decent thread to check this.

Here is where you can download a manual too.
