Rolling Road day with Got Boost Saturday 5th March
Discussion
Looks like it's a weak fuel pump that let me down here, my tuner was far from happy with the numbers it made, he's adamant it should be close to 400 and torque should be miles higher 
I did ask to have the run done in 3rd from 3k+ and not in 4th lower down but that didn't happen and he went from 2k in 4th (runs like a bag of nails if I do this on the road) No matter, at least it's got the ball rolling here to get the pump swapped out! Had a good day out anyway and nice to meet everyone/see some interesting cars 
Just had another map to try that's a little richer low down and have gone back for the standard map sensor for now until it's sorted, will then go back to the mad map & 3.5 bar sensor, so my throttle cut/boost dump problem has gone between 2.5-3k and its a tad slower up top, but he still can't get lambda down to .86 like the other stage 5 cars and this is staying around .98 so is 99% sure it's the pump on its way out.
So needs a new pump (can't find any in the uk so has to come from America) £175 plus shipping & tax and nothing upgradable like Walbro or HRC available for these as its a return less fuel system, also needs a new fuel pump control module around £40 and a I'll get new petrol cap while I'm at it as these can cause problems not sealing properly and throw a CEL. We'll get there in the end!!!
