Thanks guys for the comments.
As for the AFR's, the car was having around high 13's to high 14's at cruising and went to low 11's to high 10's at full throttle. I think thats is acceptable for what I have been reading everywhere.
The IAT was between 30 to 45 degrees Celsius (86 to 115 Fahrenheit) and the water temperature was never more than 185 degrees Fahrenheit.
Unfortunately that is all the logs I have. Maybe I can ask the guys for some more but I dont know if they have them now.
I would like to have more people take a peak at the maps and have a concensus saying either that they are wrong or they are not. Or at least like arghx said, that there is nothing conclusive that points out a huge error on the maps.
Thanks again and please keep the comments coming...

Fuel cut 1.8 bar?

Could be something as stupid as a bad tank of gas, plugged fuel filter, fuel pump voltage dropping to cause the detonation. I really don't think weak coils could do that but I wouldn't blindly rule it out.

What was your duty cycle

 

The injectors duty cycle was good. At full throttle around 6000 rpm on 3rd if I am not mistaken it was around 65%. Something around that area.
Remember I have 850 cc and 1600 cc and 2 supra pumps so it should be more than ok.

Ok, I finally got the guys to send me a picture of the housing. Pretty small and only one despite me asking many times but...
Let me know if you can spot anything strange there?
Thank you

how are your pumps set up and wired?

 

I have 2 new Supra pumps. I dont know the specific of the wiring unfortunately ( I hate leaving so far away from the shop since I can not check much and I didnt have much time when I drove the car to inspect too many things).
I know that originally they had just 1 supra pump (as some big guys here told me would be enough for 500rwhp) but they hit a wall while doing the tuning and was lowering the pressure too much after going on 17 PSI or so.
So they installed the second one and they didnt have the problem anymore.
I can ask the specifics of the installation if you think it can give some light into the problem.
Thanks.
