First and foremost, thanks for all of the kind words and wishes to get well. I am on the mend. I'm still pinging and knocking but i'm getting there!
Yes sir! I have actually completed the detailed offerings for my Stage I, II and III packages and will post them in this thread later today. Just as a quick summary, the car sits now as follows and I would call it a Stage II BUT without an LSD or cat-back mufflers:
STAGE I ITEMS:
- K&N Filters
- 82mm Throttle Body (NO IPD AS IT WON"T MATE TO X51 MANIFOLD)
- Cargraphic "Race" Manifolds without CATS
STAGE II ITEMS:
- 991 GTS/X51 Power Kit (Manifold, Cams & Heads)
- 12lb Aasco Flywheel & Sprung Hub Clutch Disc mated to OE Self Adjusting Pressure Plate
- ECU Re-Flash
Since you guys are close you need to come and visit the shop and we can go for a ride. Just bring bail money.
Thanks. 1 week from today i will be on the dyno with the car. I drove it over the weekend but I've got faults for no cats and the mixture not being right but that's because it hasn't been tuned. I am parking the car now until we make a proper file for it next week. I do not want to dyno it because i know what the curve will look like and it won't be perfect and with the amount of people watching, first impressions are everything with my baby. The power is definitely there and the sound, from inside OR out is better than anything any of us have ever heard. It's rather awesome with the race manifolds mated to the PSE. As long as i keep the button off and as long as i don't go WOT, it's actually not that bad. If you so much as wood the gas pedal though, the car goes from moderate to ungodly loud.
The plenum and TB will add top end, the flywheel helps things get spun up quicker in the lower gears and the race manifolds allow the thing to breathe up top like it was meant to breathe. The rationale at this point behind adding the 4.0L is to obtain the additional 20hp and 20lb/ft of torque. 20 lb/ft on this car would be awesome. It's not soft at all down below but torque is everything in this game.

So long as extra torque is added to the top end. There's enough down low, for excitement it needs a power curve that ramps up at the top instead of tapering off, not a general increase of the whole curve.

the reason behind going with the X51 was just this; the big intake manifold and ported heads have no taper up top like the stock car. In fact, I've noticed that when I drive the car the little orange dot defies the stock power curve on the power/torque graph on the cluster and sits way above everything and doesn't fall off.

Yes, the GT4 should be great with the X51, John.
Any chance of a warranty like AC Schnitzer is offering on its M4 ACS4 conversion? To quote Evo, 'Liberating the additional power and torque is achieved through a separate "piggyback" ECU in series with the original unit. By doing it this way AC Schnitzer is confident enough to offer a standard two-year/60,000km (37,000-mile) warranty on all drivetrain components alongside the original manufacturer warranty, extendable to three years at extra cost.'
Obviously you're doing more than a remap but there are two downsides as with any mods: voiding the factory warranty and an investment that might not be reflected - perhaps even the opposite - come resale. A warranty would solve the first problem and might even give the cred to fix the second one.
Is there a way of getting the conversion done in France?

dip in torque we see in the graph between 2500 rpm and 4500 rpm.
