My engine was rebuilt recently. Only has about 3000 miles on it. I Have the Apexi N1 dual. Why is that in lower gears like first or second when i let off the gas it sometimes backfires. Never does it when i give it gas, only when letting off. Mostly happens in first..

If your old turbo control system was broken, yes you will notice a difference. Otherwise no.

yep, in my last edition of Turbo or IMport tuner, an FD gained 30rwhp cuz of problems with the old lines, when upgrading to silicon.
