The last few days ive noticed a problem..... Say im in park and I give my car a few stabs to 6000 after like 2-3 stabs i can floor it and the revs just hang and it will not go past 4000-4500.... if i back off wait 2 seconds and stab it , it will rev easily again..... Im thinking its Fuel pump/ Filter kind of thing....... my mates recon blocked cat.... i dont think so because it would never rev... at all... its just after your above 4500-5000 for a few seconds it feels like its starving of fuel.....

Opinions would be much appreciated... Quite a bit p****d now it wont be going to willowbank with this problem

My money is fuel pump and or filter....

with that work done on a standard bottom end with a standard computer "stabbing" it to 6000rpm with no load... i'd say something is stopping it from detonating.... literally...
