it will affect your tune if you throw an exhaust on afterwards
well i understand that, but what your saying is dont worry about it until i do decide to run exhaust?it will affect your tune if you throw an exhaust on afterwards
thats exactly why im running open dp. i hope to hit 300whp, so i know it will definately benefit me.Im going to be running a 3 inch open d.p…. was going to go with 2.75 inch straight back to a apexi turbo muffler BUT when I seen the 29 whp my buddy jeff got on his gsr turbo from going to 2.5 inch exhaust to a 3 inch open d.p that changed my mind right there….
id say its due to his DP locationthe link you posted sounds like it might have something to do with the location of the o2 sensor, although usually that will be a false lean reading.
but he might not know what he's doing, still getting used to tuning.
the exhaust is being sucked back into the snail due to the fact that the DP isnt ran under the oilpan like it should be. less oxygen in the motor due to excessive exhaust funes = richI turboed my DA and pretty much have the dp stopped right where the oil pan meets the block.
