Shakesbeer i was pissed when i wrote that lost post
Squeezing more speed out of bikes was my hobby long ago so i get where your coming from though i struggle to imagine a Defender keeping up with my truck unless it has a 5 litre cummins or something in it ?
I suggest you turn down boost and fuel , move your intake sensors into the intercooler , which was the thing that finally made it all click for me , fit the Tunitand then start pushing the limits .
I have a turboT boost controller but its set at 14psi because i don't see the point in going beyond that unless i can increase the fuel in tandem .
What i have done is basically maxed out the factory settings because the digitally controlled fuel air mix is likely far more accurate than anything i might bodge to beat the system .
The mrs drives a bog standard KDJ90 which is said to have 163 hp from the factory but she says my truck flogs hers and i reckon a chip could only improve it .
