VF1 Tune MAF vs MAFless

[Steveaa]

If you're on the fence about it, there's a good chance you will end up getting them anyway. Best to get them now before your tune or you're going to be forking out another $800 or whatever they charge to have it re-tuned when you shove headers on the thing. I didn't do headers because I was happy with what I got from just the OTR and tune, and if I do get them in the future it wont be for like a year or more so I'll deal with it when I get there.

Decided against headers. Can't justify the cost for a measly 10kw

What about the torque? Why not just get some cheap HSV headers?

 

[PeteSS]

Yeah, was thinking of getting some used HSV VE Tri Y's, but have been told they're not a straight bolt on item onto a VF and that the gains would be very minor.

I'm guessing it's about a 20nm gain in torque. Not small, but not earth shattering either

Headers are more of a power adder later on when you have more mods to go with. That being said though they do make a substantial difference to how the car sounds, you will get more of a beefy note with a full system. If you run stock bits up front and then a catback, you have restricted air coming out into larger pipes and that's what resonates and ruins the note.

Correct with more valve train noise as well and on top of that a 3 inch system is less likely to drone than a 2 1/2.

Got the car back today. Went from 209rwkw to 245rwkw. Pretty decent gain from just OTR and tune (assuming I got the bhp to kw conversion correct.

Only drove it a short distance so can't tell if noticeable gain in performance, though it sounds a shitload better

 

[Steveaa]

Pretty much the end result RWKW I got from mine, I think mine may have been 243 or something. But the sound difference alone made it well worth it. For me the main thing I noticed if you just use the Automatic (if i recall correctly yours is and they did the shift points for you?) is the shift points are much nicer.

 

[PeteSS]

Yeah, the gearbox feels much better now. Felt very lazy before.

Definite power difference to before, now that I've caned it a bit. . And the sound with the marriage savers gives me half a mongrel each time I give it some

Afm turned off?
