That thing will be a beast.
I have an LS1 in my cobra with magnussun supercharger. It made around 355kw at the wheels. It drives fantastic, very user friendly. These things produce bags of torque almost from idle therefore you can light the tyres whenever you like and you don't need to run it up on the limiter to do it.
I'm only running 4lbs of boost so it has a lot more if I want, but at this point it is very reliable, not stressed and makes me grin like an idiot every time I drive it.
I am running a Lunati blower cam which was made for supercharger/hotrod applications therfore has quite a lope so it sounds like a cobra should, (ANGRY).
With regards to the IM240, I managed to pass first time with no blower and a stock tune.
There is some major points to note.
Use quality cats. I used cats from an XF falcon ( yes you read it right) those old cats were quality.
A lot depends on who is doing the drive cycle on the dyno because anything they do can have major effects on the outcome.
A lot of these cars fail on the deceleration not acceleration.
The Maf needs to be placed ideally 400mm or so from the TB so the computer has time to make adjustments.
Try to get the distance of the O2 sensor and cats close to where they are on the OE installation.
Get a new carbon canister and DON'T hook it up until test day cos it will feed fuel vapor into the engine from soak possibly increasing emissions.
I used a painless wiring loom for mine which included drive by wire and it was a breeze.
Only thing I had to do was reverse the pedal due to being L/H drive pedal.
Use the parts they tell you to and you will find it quite easy.
Can't wait to see it on the road !!
