Lost a load of power just after changing the fuel pump to a 450lph pump as I thought I was running lean on the old pump
Not good at all and I could find the issue so came to the conclusion the car was running that lean on old pump that this is now where the car is power wise
But after cleaning the air filter I found this
The filter had collapsed on itself
Any swapped it for a other apexi filtered ( borrowed )
And all was good again
Just need to fit the re big filter and LS4 TB when it arrives and full remap and fine tune
Looks like this might reach 360hp
