no cause it depends. make a run in each gear, 4th might be a tad better, but on a non turbo, its going to be less than 5hp difference

You should try to dyno at as close to 1:1 ratio as possible. On most cars, that is one below top gear.

it was the difference between 120 hp and 150 hp! im running a s5 n/a engine, with full exaust, intake, safc ect with about 130k or 60k depending on wether the rebuild was a lie or not.
i ended up in 3rd with 165 hp
now ive pulled on a 03 mustang v8
but my friends s4 similar mods minus the safc and header FEELS faster. may be due to my removed ports and wired vdi.
