- Still haven't found what's limiting the tune at 8000rpm. A few tuners have confirmed that it should be possible with 04 ECU, could be the tune itself. Also had another theory on cam sensor gap, need to investigate further on that side
- Decided to try A2W intercooler to reduce IAT. In discussion with Frozenboost for the setup
- Might upgrade the injectors to 1700 and have the tune adjusted for a few more psi in spring
if you are going through the trouble why dont you go with an aftermaket ecu?
