Some statistics from analysing the datalogs of both runs.
11.714@120 11.693@125 Launch RPM 2,800 2,700 Launch Boost 5.12psi 3.64psi I changed gear 1st-2nd at 5,000rpm by the BMW tacho to allow for the lag in the gear change, speed of acceleration in 1st gear and the lag in the BMW tacho. Max RPM in 1st 6,771 6,784 5,000-Max RPM 1st 0.48s 0.56s Boost drop 1st-2nd 12.96>10.38>12.86psi 13.48>6.11>10.24psi Duration of boost drop 0.32s 0.46s Max RPM - 2nd 6,887 6,803 Max RPM - 3rd 6,725 6,590 Max RPM - 4th 6,269 6,539 I need to remove the boost drop 1st - 2nd as it is costing me time in building the boost back up. The rest of the run is quite good with the max boost reaching 26psi for a split second. |

Yeah mate that boost drop is costing you an initial 0.14 seconds. What tune are you on again?
Have you tried launching from 2nd gear?

I haven't recently tried the second gear launch but it is something that can be tried. I have tried it in the past without success i.e. times were slower than using 1st. |

Sounds like you know whats going on there. From memory i received the 4psi switch (correction, 15psi). Im going threw a whole lot of Overboost & Underboost fault codes at the moment. Waiting till tomorrow to fill up with E70 and take another log

The Hobb switch on the TBI comes with the boost trigger set at 15psi. The trigger setting can be changed up (clockwise) or down (counter clockwise) using a 7/16' allen key. I will log the HPFP performance next time I run and see how it is handling the extra flow requirements of the E60. It will interesting to see how yours handles the E70. I cannot see how the TBI would be causing your overboost and underboost issues. Hope you sought it out soon.

Thats some pretty detailed analysis you're doing on your 1/4 logs Coupes33 love it. Agree the boost dropping off is costing you a bit. I also logged my 12.3 sec pass on the stockers so will compare and see how my one looks with respect to post shift boost drop

This is a Tribela custom tune we are working on, hopefully he can get to the bottom of it soon as its costing me a fortune in fuel (on my 2nd full tank) and risking my licence unnecessarily

Just ran a 12.1 @ 118mph (FBO stock turbos e60 MHD custom flash)
Imrovement from 12.4 last month. Car has remained the same (with crappy street tyres 265 kumhos) just brake boosted slightly higher 1700 rpm and shifted manualy. I reckon could get a high 11 with some nitto's |

What is the boost sensor "A" circuit? I wonder if this a DME issue? I installed a new DME with the later IJOES software. Any thoughts from the tech boys??

Yep shifting as soon as I hit 6000 rpm. I dont have a1 kickdown blocker so launching in 1st gear. When I launch should I shift earlier i.e. before 6000 rpm? And is 6k shift right for all other gears? |

Remember shifting at 6000rpm is more like 6600rpm, try closely watching your tacho needle next time you go down the track you will see what i mean. Whats your drag setup? How much fuel? Whats your average ignition at in the logs? A bit of octane may help. Passenger seat removed? What tyre pressure? You getting any wheelspin? What suspension are you on?
