Legacy_Guy Posted August 13, 2014 Share Posted August 13, 2014 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 limithttp://forums.nasioc.com/forums/images/smilies/eek.gif. 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. Thanks! https://docs.google.com/spreadsheets...it?usp=sharing https://docs.google.com/spreadsheets...it?usp=sharing http://i717.photobucket.com/albums/ww176/subydude1983/Aug123rdgearpullVD_zpsbb304285.jpg Link to comment Share on other sites More sharing options...
McDowell Performance Tunin Posted August 13, 2014 Share Posted August 13, 2014 Timing drops really low (6 degrees on one log). Even with 91 you should be running more. Also, the bit of high rpm/load knock. You would really benefit from a custom tune, versus the OTS map. There is more power to be had by simply adjusting your timing. www.facebook.com/mcdowelltuning [sIGPIC][/sIGPIC] Click Here for Stage1, Stage2 and Stage3 Tuning and eTuning Info Link to comment Share on other sites More sharing options...
