Ok so after careful review, you aren't actually wrong about the last part, you are wrong about the first part.

The only reason you 'USE' more fuel at peak power is because the injector is doing it more times. Peak torque has a higher ratio of fuel usage per rpm compared to peak power. Which is why most fueling and ignition problems occur at around that time but become better as rpm increases.

So, yes, more fuel will physically leave your tank at peak power but you certainly have a higher demand for fuel at peak torque

What you just said is exactly what I said, including you using the ratio of fuel usage to rpm instead of what I said (which was just to say per cycle). So either we are both wrong about the first part I wrote or neither of us are, and I really prefer the latter.

Most ignition problems turn up at peak torque because BMEP is highest at that point, making the mixture harder to spark off.

A lot of fuelling problems turn up at peak torque because that's when it's likely to ping the worst (and hence where pinging will likely start to show), given that BMEP is highest then.

I will quote that part you are wrong about:

"Now that's just untrue"

And yes, we are saying EXACTLY the same thing lol. You are just saying it a different way.

I think I've had this conversation before!!

ok just an update didnt get a chance to do a fuel presure test as when i got hoe dad had taken the car but when he got back told me to take it for a run and the car is runing a lot better still has a little pop above 4500 rpm but its runing a lot better and is holding 7psi of boost now so might pull plugs out and check them and clean them and see if the gets rid of the little pop thanks for the help guys will let ya know how it goes
