    If it’s original it will be rotten, very soft.

            EFR7163 made 592hp / 760nm on ethanol. On gasoline little over 500. Full boost around 3.5k.
            Bigger is pointless, smaller probably too if you're doing a full build.

                  I replied in post 3. Get rid of that other diagram.

                    Finally got round to doing the leak test I’ve blocked the pcv valve and put air in the maf hose end and as I blow air in it comes straight out but I can’t see where it’s coming from I’ve sprayed the hoses with soapy water but no luck am I doing something wrong?

                      You do get air escaping via the block. Don't put too much pressure there or there is a danger you can blow oil seals. Set the pressure to about 15psi and get someone to look for leaks whilst keeping it there. Two person job I found.

                          Sounds like you’ve got a big hole.

                            Have a look for oily residue, always a telltale sign

                              Can’t feel any air blowing just loud air escaping checked all clips car drives normal even when you accelerate slowly the car picks up pretty quickly but when you plant it that’s when it becomes a kangaroo. I have a test leak kit but I’ve not done a test on the maf hose before only the one my kit fits but as said can’t remember how

                                Is your fuel pump good? I had this and it was the pump. It couldn't keep up on boost and therefore mix was weak and boost cut by ecu.
