Hey guys, as the title states when I'm wide open throttle on full boost (4000-7500rpm )it misses, coughs and splutters and does not perform at all pretty much all of the time, 95%. And also when quick shifting between gears at high rpm like you would when racing, it cuts out for a split second. Its only been happening after its re-tune. I've taken it back and he assures me its not detonating but thinks it could be cooler piping squishing or the fuel pump.....

Just after any useful input on how to solve the issue....

Mods are;

Id1000cc

Bigger rail

Sard fuel reg

Forward facing plenum

80mm throttle body

Lowmount replacement stock turbo

3" exhaust

445 walbro

Adaptronic ecu

Rollin automotive front mount.

Spitfire coil packs.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      Had a chat to Tony Mamo - he advised that looking at the graph's shape (regardless of number translation) it shouldn't be levelling off like that up top. He said it looks like the car is running a restrictor plate or something of that nature. Luckily the last dyno pull on E85 was saved to the PC - So I did a quick trace of Barometric KPA vs Intake manifold pressure, and lo and behold I see a copy of the 'waves' I was seeing on the dyno: I'm not entirely sure how to go about addressing this. It may be worth sacrificing IAT to run a more direct intake for the motor. Though packaging this could be flat out impossible given the constraints of the car. I should have removed the intake pipe to see if this made a difference but looking at this graph I now have something to potentially test in the future and think about.

      Oh, I forgot too, all the multimedia stuff captured and sold through things like people playing Pokemon Go. Pokemon Go specifically, can actually be traced all the way back to a CIA investment company too. So yep, they're watching everything. Not to mention the new stuff where they've worked out how to use WiFi signals to be able to map occupants inside of a building. That one would be something that I see being more used in public/government buildings, as you need to understand the signals when the room has no one in it first. It's not as easy as Hollywood would like you to think it is.

      Followed ☺️ Assuming those are NEO rods, then at least 400kW all day.

      Great work! Give it a clean up with some Emery paper, and I'd run a thread die over the threads too to clean them up. It will make reinstall much easier, and also life easier for the next time it needs to come out.
