so saturday on way back from santa pod i did some angry logs,
4th gear high boost,
20psi@ 4307rpm
5th Gear
20psi @ 4259rpm

Boost control is still in open loop as i've had issues with the tps signal not being right, as you can see it tapers up to 100% not a sudden 0-100%. Not sure why tho, new sensor, new loom, grounded as per instructions, calibrates and operates fine with engine not running
After the 5th gear run i pulled the plugs and no signs of det but signs of too hot, i fitted new plugs before pod as the old iridiums i couldn't read properly having cleaned them so much in the past.
New br8es got fitted but they still read a little hot, luckily brought a set of br9es at the same time for around £7 a set i'm not complaining lol
In the 5th log you can see the bottom green afr line drop to 10's coming off the throttle, thats the issue i think is slowing me down massively
Hopefully 1psi less fuel pressure (back to 4psi), 1st stage jet change smaller and a good blow out solves it.
Dyno has now been booked for next week wednesday night local to me on a relatively new dyno-developments rolling road so hopefully get some sort of bhp figure i know i wont have Boost plotted but i'll be datalogging at same time so not fussed, will be nice to see what its doing then see how long I can get to try make any more before the owner wants to go home
