Will consider my options, probably go for 550 injectors and an uprated fuel pump, and get a full remap to take advantage of the air filter, 3" exhaust, etc.
Not sure of the likely bhp outcome but I'm opting for a safe remap rather than a hairy premature engine-wearing one.

If you're ever in doubt about your knocklink working, fill up with BP Ultimate, worked for mine 
Tesco's in Peterborough have 99 octane SUL I believe, you'd be better off there. A lot cheaper too.

The Tesco pumps in Boghorror still have the old red pump handles and are badged as LRP. It's not 99 SUL.
I asked the store manager during a Tesco complaint on Tuesday night - they had 2 for price of one offer on Lucozade Sport. It was cheaper than I can buy it at Bookers cash and carry for my gym, so I put around 200 bottles in a trolley, loaded them on the Brucey-style conveyor belt and was then told it was store policy I could only have six and I had to put them back. Lol, don't think so. I don't want any now. Put 'em back yourself since you can't be bothered to display your store policy prominently.....

Ping/det/knock etc can all be going on LONG before you can feel or hear them yourself. Add to that noisy freeflowing exhausts/intakes etc and you will only notice it when it's to the point where the big red light would be on which is too late really.
Whatever jedi powers you may think you have.
And yes I've had plenty of much older more basic cars including turbocharged ones etc so I know the point you're trying to make but you're off the mark I think.

Sounds like you've holed a piston. When you open the throttle the boost pressure goes through the hole and compresses the air in the crankcase. This then forces the oil through the breathers and back into the induction which causes all the smoke. All that extra volume also drops the boost pressure.
(Speaking from experience - in my old Esprit Turbo I managed to burn nearly 6 pints of oil in 30 seconds and completely covered both sides of a dual carriageway in thick smoke)

If it wasn't for the Knocklink, I wouldn't have known the motor was detonating - it's not audible.
If I hadn't known it detonating, it would have gone bang on the particular cylinder it was detonating on.
The days of plug chops are over, my friend.
You don't like electronic gizmos, that's fine - let's just hope you never suffer with a semi-blocked injector, maybe from fuel tank crud because, without a Knocklink, you'll never know - it's symptomless to the ear and the car's performance remains just the same. Simply put, the fuel drips rather than drizzles, gives you a poor spray pattern and .... bang if you're unlucky.

Exactly what he said. Yes it mine have just needed cleaner this time but if for some reason you get a lean mix going through with no afr gauge or knocklink your car will go like stink because of the lean mix will knock its **** off and you won't notice until it's damaged.
Yes you can audibly hear knock inside the car when it gets extremely severe and that's when bad damage is happening.
Prior to that it's still a very bad thing but inaudible without the use of det cans or a knocklink.
Laugh all you want at our 'electronic gizmos' (luddite) but I like to know when bad things are actually happening beneath the bonnet, not simply think I know because nothing's gone bang yet....
