Well, few problems today.
It ran up fine, he did a fair bit of low end tuning first with no issue. Water level didn't drop, temps were under control and dropped back as soon as he backed off. All looked sweet until this weird missfire developed. Lucky there was a donor VQ25dd at the shop, I swapped some coilpacks around and found it wouldn't fix the issue so next I checked and gapped the new plugs. Again no issue with them. We decided to check the fuel side and found one of my Walbro's wasn't pumping properly causing it and after topping up the tank all was fixed. Looks like I am upgrading the pumps again...
The tuning continued, we decided on a safe 26psi tune which in AWD and with extra correction produced 310kw. I may drop the shaft and push for a good number some time later, once I am sure the engine is fine, but for now the car feels very strong and great to drive on the road. Definitely faster than before.
I have ordered a new set of 4000 DBA disks with A1RM pads for the Brembo's, that should sort out the brakes, then its ready for Phillip Island when I can get there.
