Sorry I am late to the party as usual, but here is what I hope is some helpful advice. Don't change multiple pieces of hardware on the car at the same time when tuning. I would recommend tuning the MAF or injectors in isolation rather than trying to tune for both of them at the same time. Currently you don't know if a miscalibrated MAF or injectors could be causing your problem. When I tuned my car I started with a stock file and K04 turbos with 60lb injectors. Then I tuned the injector latency and scale based on long term fuel trims. Once the injector constants were stable, then I switched to a larger MAF, and again used long term fuel trims to determine the MAF linearization table. Only after the injectors and MAF were stable did I ever turn up the boost or attempt to tune AFR and timing. This is the same approach that the books written by Greg Banish recommend. Also, the NefMoto stage 3 base tune should probably be called an example tune instead of a base tune. Not to mention it works well on my car, and not always on other cars. If anyone can tell me what is non-standard about my car I am all ears.  |

Well I did some more playing.. less agressive settings on IOP, more changes IRL and complete remap and scaling of LDRXN. The car feels very solid and fast now, with no noticeable bucking/timing drops. No logs because it's raining here.
Also strange thing, I think properly scaling LDRXN fixed my rich light cruise issue because the AFR's are perfect now!
I'll try to have some logs soon to see what I am (not) feeling is true. I'm betting it is though!

fantastic work! I'm looking forward to seeing your logs. I think e85 should be in your future, the timing you can run is amazing.... can't remember if you did rods or not though. If not, they will need to be done for e85. I think you could see 550 whp.

Yeah, I wan to do some logs... I take a few when i get back from OC though. I would love to do E85, I specifically bought 1000cc injectors for it, thing is there is only one gas station in all of Ontario (really there is two, but the other one is 6 hrs away), and they don't sell E85 to anything but FlexFuel cars. One day I'll get to it though! And no I don't have rods... but IMO our motors are good for over 500whp on stock rods  |

This was with a hard mounted LM-2. |

I'm not saying it's not possible to window your blow or bend a rod with less power... as the tune will dictate how well your motor will survive. But I've seen far too many people with aggressive tunes on K04's running win the 480-490wtq range early on in the RPM band (something I will never see). Besides, if it happens, it happens |

480wtq with k04's? i need to see a dyno / spec sheet on that... i've yet to see a dyno chart of a k04 car over 450wtq. 605's are another story, but anyways thats a power level i've never heard quoted nor seen a dyno chart about.

There are a few E85 K04 cars that run it... and there is at least one FT car that is doing it on pump + meth

One thing I started wondering last night...
Are you planning on releasing your Tial 605 tune to the community when you feel it is stable?
By no means should you feel obligated to, but it is always nice to have another tune to compare techniques to.

That was at 22psi. 100k miles on the motor, stage 3 since about 43k. It was about 435 wtq. Was going well into triple digits in 5th. Pistons were clean, nothing abnormal. YMMV, but it can happen. |

if you put a hole in your block @ that psi on K04's with that kind of power something else happened. It wasn't from too much power I'll tell you that much.

I'm pretty sure i know a guy with a ko4 e85 tune that runs close to 480 wtq... I don't have dyno numbers that support this, but I do have a folder full of logs that suggests close to that. back to back 3.1 second fats but I agree 605's are another story. On e85 they can do 530+ wtq easily. |
