Whipple knock help
I recently installed a whipple kit on a stock motor. Im running about 7psi at 5000 ft elevation. Johan is doing the tuning and everything was going great until the last few days. I recently started to get some heavy low end knock. The last log shows 8 deg ST and 2 deg LT at 23% throttle at 1500 rpm then 6 deg ST and 6.5 deg LG at 65% throttle and 3900 rpms. If i can get past the low end knock WOT is perfect no knock 10.8 AFR threw redline.
Since the problem started I have reverted back to some old tune revisions that had no previous issues, completely drained the fuel in the tank and refilled with shell 91 octane (from the same station I had success with earlier), and re-torqued every exhaust bolt i could find. By hand I can find any metal to metal contact when moving the exhaust.
