I removed the in-tank filter and bypassed the hose from the pump directly with the external connector. Used a Cevrolet Vecrtra EFI filter and noticed it allowed a lot of fuel flow pass through... when I connected everything I noticed that the fuel pump was not doing the same noise, and when I turned it on, the injectors star doing a noise like they have a lot of pressure. Accelerated to 6000 rpm and let the throttle... when revs passed down to 2000rpm did a sudden acceleration to 2500 and then back to idle... it was estrange... so I went back to the original setup... Any suggestions?... I will try with a new filter from other car or EFI bike to make sure the issue was the new filter...
