1BADBURB Report post Posted May 22, 2015 I recently installed LOC and Fabspeed test pipe and wanted to make sure the AFR (air to fuel ratio) was on point. I was told by a few that the AFR would lean out a bit and it would be unsafe, thus needing a tune. After the 7-8 dyno pulls, it was verified that AFR was 12.5:1 low rpm and 12.1:1 at WOT. This is plenty rich and a safe tune. So in conclusion, you don't NEED a tune to correct the air to fuel ratio. However, I have seen thru my research that a tune highly benefits the egear guys in terms of shifting. I was also told the performance gains of 15-20 whp can be had but I have not seen concrete proof of it. So, here are a quick few vids of the pulls. My most fav thing on this car is the flames she shoots out... Enjoy! And a vid with the go pro on the bumper. Quote Share this post Link to post Share on other sites More sharing options...

1BADBURB Report post Posted May 23, 2015 I never was able to dyno before hand bc it was winter. Sorry... But I'm willing to bet it's at least 20whp gain. Quote Share this post Link to post Share on other sites More sharing options...
