hi,

i log the fuel pressure and on wot it go's to 400kpa and this is fine if we keep below 1bar boost....

but as these cars run 1 bar stock... we are doing 1,5bar boost.

Opel insignia 19-zfb-4 full stock read.hpt

i changed all paramters in fuel pump for 600kpa fuel pressure but without any luck.... fuel pump DC is only 70 so plenty of room there.

in Winols i chage fuel pressure request in the engine ecu.... but HPtuners doesnt support these parameter neither are they willing to put them into the software....
only thing they say is give us the iD of the table...... if its not there i dont have a id .....


anybody knows any tricks ?
