It was with an upgraded BBSC Novi2000. We were running the car with rc550's and Tec3 ECU. Denso 350 Fuel pump. That's what he used in his turbo cars. From what he saw the rails were fine. He said he was running out of fuel due to volume on his cars. He never looked to see if the OEM lines were fine with our setup, he just changed them.
Fast forward to today. I have since put everything back to stock. Running my turbo setup, same injectors, AEM and a Walboro fuel pump. Pretty of fuel for 420 HP
