Hello LegacyGT.com. I installed my Grimmspeed downpipe over the weekend and finally got around to doing some datalogs yesterday. To me these logs look ok, DAM looks good but looks like I have some knock in some areas. Can someone with more experienced take a look at these and let me know how they actually look. Logs were done in 3rd gear as a 4th gear pull puts me at double the posted speed limit
. Aside from a LWCP, turbo back exhaust
and a Cobb Stage 2 map, I have done no other power mods, I am running Shell 91.
