For some reason the headers map pulls noticeably more than the all catback map that unichip said was likely to run best. I also asked, and they say there are no risks in running the headers map, as long as the map is for the correct intake...

I personally enjoyed their most consevative mAp which was timing out fuel in

Honestly, its a waste of time and money now that i have had the experience of a proper tune. Sorry for the brutal honesty.

Care to share differences/preference reasons from your experience?

how do you feel with the fuel + timing +?

I think he's coming to the conclusion most either have or will. Unichips are great, if they're all that's available they'll do the job somewhat well. That said, you'll never get anywhere near the kind of control you can get with a now-cheaper reflash. Without low-level control of all the various things, achieving good results is very difficult, or impossible in some cases.

Unichip can't:
Scale port injectors directly (I.e. Without a maf hack)
Scale direct injectors at all (no e85 for you!)
Modify knock control parameters
Adjust advance independent of base timing
Control di/port ratio (crucial to getting things right in the first place)
Adjust dbw maps
Many, many, many more

So basically you can't really do anything with it beyond tricking the ecu into adjusting fuel or timing. None of the vast subie knowledge on the Internet applies, can't use the common tools, and there will just be many issues that simply cannot be properly fixed with any piggyback because you just flat-out can't do what you need to do.

On an NA setup, with just bolt ons, does anyone know how that actually translates to HP??? I'd be surprised that the difference be substantial between bolt ons supported by Unichip vs Ecutek or other flash.

probably not much if anything in terms of peak hp, except maybe from the ability to adjust cam timing. driveability and the stability of the tune are the biggest benefits i'd say. of course once you consider the ability to run e85, it makes a lot more power lol.

i think unichip is probably the best piggyback out there, but it's still a piggyback, and there isn't much need for them when flashes can be had so inexpensively.
