Got the boost down lower now, still makes 265 rwkw, so the set up is great now, ramps up earlier and pulls so damn hard! wharts more even tho it was hot, we did run after run and the power was repeatable so heat wasnt too much of an issue
did have fuel issues again, turns out my walbro intake which feeds the external bosch was breaking down internally and causing a restriction.... also turns out that its not a genuine walbro and its a copy!! all this time i thought it was a genuine! dodgy shit, only way to tell was to put a known genuine one side by side with the copy and look internally where the filter pick up goes. externally they look exactaly the same.
MASSIVE THANKS TO JEFF TSL AND THE BOYS FROM TURBO TUNE!!!!!!!!!!!!!!!!!!!!!!!!!!!
