timing issue???
Hi Guys,
I'm having an issue with my setup. TPIS burned a custom chip for me and the timing is suppose to be at 6* and fuel pressure at 43psi. However, when I set the timing at anything less than 10*, I get a pinging/pop noise around #3 when I step on the gas good at idle.
I'm happy it's finally idling better but now I'm not getting good throttle response and I'm assuming it is cause the timing isn't the 6* the ecu is programmed to?
FYI - I have the fuel pressure at about 44psi (idle) right now.
Any advice would be greatly appreciated!
Thanks!
