Installed HFC, do I need a Stage 2 Tune now?

[Andrewiffic]

I am already on Unitronic Stage 1+ and I just installed a 034 Motorsports HFC. I went for a drive and noticed a little bit of power increase, especially down low. I don't have any CEL on that I know some people experience. I'm just wondering if I get the Unitronic Stage 2 tune, will it do anything?

I'm also considering getting a high flow fuel pump upgrade in the future, so should I just wait till I get that and then get a tune to Stage 2 HPFP?

So no down pipe just a high flow cat, no tune required.

Check the unitronic site for stage 2 requirements before you change anything more.

No down pipe, no. I have looked at the Unitronic site, but I've also read on the forums that some people said a stage 2 tune doesn't do anything besides remove the CEL if you have one. I've also heard that most of the gains found are from the HFC, but I'm curious to know how much more power I would see from getting a downpipe as well?
