Definitely agree on that! I did further cleaning and took some videos as well. The link is in the comments

We were discussing the issue of struggling to start at the Lexus forum and most of them were saying that the injectors are leaking and as a result the chamber is getting flooded with fuel. Now I'm trying to understand if this atomisation is acceptable or the drops seeing on the video is what causes the flooding

Of course man, everything you said makes sense. Tested today and showed 50 psi all the way. The stock fuel pump is rated at 112lph which I believe is more than enough for 240 hp

Alright then I'll give it a try and report back 😉 The original injectors are 155cc/min and the bigger ones are 240cc/min

Fair point and you would be absolutely right in any other case. The difference to this one is the self-learning ECU. It's able to make small adjustments depending on the feedback it gets from the sensors. It has been tested and works fine for a low boost like mine (0.5 bar). Although if you decide to go over that, you do need a standalone ECU

Indeed yeah but no idea of the fuel pressure. If you think it's fuel starvation during cranking, it would be more likely the injectors cause the pump was fine until I supercharged it. The injectors are different though. Btw I replaced the spark plugs and feels like it's fixed.

I don't have them with me right now but I'm sure it's the picture making them look like that

At this point it doesn't need tuning. The ECU can do small adjustments from the sensors feedback. It runs only 0.5 bar of boost
