Then you have a problem with your car. It didn't do that when it left the factory so really you should look at resolving whatever the issue is than buying aftermarket snake oil.

 

Any sensor on the car when faulty can cause 'flat spots'. Air leaks on the inlet tract can too (in relation to MAF). Best to get a garage to diagnose which sensor is faulty rather than you potentially wasting more money randomly replacing them one by one until it (hopefully) goes away.

i got my own fault code reader and it dos not report any think wrong with the sensors or any think else plus i have a vacume guage that dont show any leaks

A sensor can fail "in range" and not flag up a code on your scanner, yet still cause a running issue.

yet another tuning con with false claims! dont bother mate.

 

I had similar issues with lambda sensor, engine overfuelling it seemed. Check all your sensors

i have had the car on diagnostics computer there are no faults with the engine at all

 

There's a fault with something if you have a noticeable 'flat spot'.

 

If you've already made your mind up that this valve is going to fix all your 'problems', then just say and we'll tell you what you want to hear.

Code reader wont tell you that the cat is a bit blocked, the MAF isnt working properly or if there is an air leak on the inlet somewhere.

 

It needs closer looking at i f the flat spot is anything more than normal (zetecs do have a natural flatspot) then I wouldnt be looking at fitting a FSE valve, all you do with that is risk ruining the fuel pressure.

i have not check the cat i have fitted a new exhaust from the cat back i might fit a new cat

 

zetecs do have a natural flatspot

 

You mean this barely noticeable dip in the power curve? :)

I doubt anyone is really feeling that in the car.

i take it that the top line shows the flat spot between 3000 revs and 3500rev well that were i notice it
