R9KTuned got back to me today, they quoted 400$ to flash the stock ECU if you replace the injectors with 550's and maintain 45-50 fuel psi (New pump and AFPR). Doesn't sound bad if you're not looking to get involved in the standalone worldYou recall what didn't work out about it? I thought it was more that he didn't have a good tune that caused the engine damage.. not that the software didn't work?
In my 2GRFE, I'm running 5.2 psi (6lb wastegate spring) with 440cc injectors, DW200 fuel pump, Aeromotive AFPR with 93oct on a R9KTuned reflash and it seems to be running great with my midmount turbo setup. Plan on trying to dyno soon and hopefully turn the boost up slightly with my EBC.
I've had issues with cv axles lately when launching so I may switch my wastegate spring out for a 4psi one. I'll use a "boost by gear" feature so that in 1st gear I can hit 4psi wastegate pressure then have increased boost pressure in the other gears.
