That's quite a big gain , around 10%. If you managed to do that with off the shelf used parts you have done well. Back in the day we all fitted a 4 into 2 into 1 manifolds and a K@N air filter. A 10% gain was rare and if you saw a gain at all it was all top end , red line stuff. Your upgrade is mid range real world gain, well done!
