APR Stage 1 and Carbonio

Well I have tried both Carbonio and Twintake.
As far as Carbonio vs. Stock goes, this is the difference I had measured in near identical conditions (back when I was stg1)

Stock Intake:
002: 6640rpm – MAF varied between 238.--g/s ~ 240.--g/s
032: Long fuel trim +1.4%, Short fuel trim -3.0%

APR Carbonio:
002: 6640 rpm – MAF varied between 244.--g/s ~ 247.--g/s
032: Long fuel trim +1.4%, Short fuel trim +0.8%

Twintake on the other hand is a true CAI and will give you a decent power gain up top (I haven't done measurements cause the readings are not accurate when you remove the stock MAF housing) much more substantial than Carbonio in terms of power.

Why don't you put the HPFP also, together with stage 1+ ?

The numbers are even more interesting...

This this and this times 100. I did the rebuild while APR had their fall sale so it was like $550ish.

2 things you could do to avoid down time on the rebuild.
1. Try and jump in the pay-it-forward initiative that was started on here by a member (copizza iirc) who bought the APR unit and offered his stock unit for the community to use for a rebuild by APR.
2. Try and find a local shop that has a "trade in" program where they ship out a spare oem hpfp to APR for the rebuild, call you for install when it comes back, and take your old hpfp for the next guy.

Either way, it's worth it!

This set will do 13.8 with a better launch it could get down to 13.6. I'm going to get a rebuilt HPFP during APRs next sale.
