Ign at 24 at &.8psi from 7000 rpms problem
 
Ign at 24 at 6.8 psi from 7000 rpms and up?
My car is at 24 at 7000 and up at 6.8psi and still it feels fat
A/f ratio 11 ~10.8
Its feels like she needs more ign
From 6800 the exhaust temperature goes very hi
Knock sensor never show more than 0,4 volts so i think that still not knock there.

Im working for the perfect map at 6.8 psi for everyday use

Mods
Single turbo gt35r 86 hta ar1.06 T4 (atp)
Big intercooler
3mm apex seals
Pettit street ported engine
Nipon denso supra fuel pump
850cc primaries
2225cc secundaries
Aem ems
3" free flow exhaust from the turbo till the exhaust tip


1st to 3th i dont feel a big issue but on 4th it don't go more than 7200rpms and the exhaust temperature goes very hi
I quite lost about it cause its seems like it need more advance but it is at 24 degrees , i don't want to ruin my engine to figure out if that was the problem.
Plus could be the turbo cause it is so big that at that low pressure could cause the problem , but I'm not sure 100%
Fuel pressure is OK , i have a electrical fuel pressure gauge.

Im lean it up and it seems get better
Im just amaze that im working with 24 degree at the ign
I just working to get a bulletproof set it for the street
And then i will go for 15 psi
It looks (as virtual duno say) that she is making orroung 280whp at 6.8 psi not bad at all
Will be nice to know if somebody have similar experience

1) post a datalog
2) post your calibration file
3) where are you measuring the exhaust temperature and how are you measuring it
4) what is your definition of high exhaust temperature
