I have a procharged ls1 with a walboro fuel pump when i got my car tuned the tuner said i was runing out of fuel at 4800 rpms. When i put a pressure gauge on it i was right where i needed to be pressure wise. To be safe i was thinking about putting the harness on my fuel pump to increase the voltage to the pump to get a little more fuel is this safe to do with out re tuning? Not looking to spend alot of money just want it to be safe untill im ready for a real fuel system and a forged motor.
