Good question cos I am going single and have read so many horror stories about fueling. Needing huge injectors, pumps and ecu,s I am trying to get the microtech LT8S but its proving hard to get the money together and get all the other parts needed for the conversion before rotorstock. I have been searching like mad to find some answers about fueling and boost control for a TO4E ,V mount and the rest stock...

on stock fueling and ecu will i beable to run the turbos at 12 psi non sequentil with a down pipe? or is that asking to mutc?

DONT RUN THE STOCK ECU OVER 10 LBS OF BOOST!



You WILL blow the motor. 2 more pounds of boost (from the stock twins) is NOT WORTH IT!

I ran my stock fuel system 12psi. after the bigger pump ran 14psi. when I wanted to finally kill the car I was running 16psi. BTW my motor and turbos did not die of a fuel related problem ha ha ha wooo woo I beat the piss outta my car just before the coolant seals finally went

you can run more than you think safely IMO.
