Perhaps a better question is who would buy a chip for a naturally-aspirated engine? At least with a forced-induction engine you can expect to get meaningful power gains from a change in programming.
I dunno Stew...does 26hp really matter when you already have 275hp? I doubt it. Now, 50hp definitely matters when you have 150hp.GIACs W8 chip gives a 26bhp gain at 6,250 rpm (at the wheels)
and 17 lb-ft of torque at 2,750 rps (at the wheels)
The 100 octane file adds another 10bhp and 7 lb-ft at the wheels.
And that on a Tiptronic equipped 4Motion.
35/24 gains at the wheels would be equivalent to a moderate 1.8T chip?
I would say those are decent gains for a normally aspirated motor.
The W8 does have infinitely variable intake timing and 2 setting exhaust timing.
The V6 has two setting intake timing only, no variable on exhaust.
dsusexaethera, I have to tell you that even Naturally Aspirated engines can benefit from chipping. Changes in the fuel mapping from ECU upgrades not only slightly increases power but changes the torque line and other items. Using the W8 chipped with GIAC's ECU upgrade as an example, the first major benefit is a huge for the 6-Speed Massive: removal of the 1st gear rev-limiter. This is an inconvenience for many W8 owners and it allows you to experience the torque of this car. Another great improvement is the mid-range and high end torque increase! Stock W8's have excellent low-end torque but at highway speeds the power drops off, but when chipped there's more power that's available after the 80MPH and keeps going until you max out. Lastly there's the improved fuel economy found with changing the ECU mapping. I noticed an increase of 2-5MPH after being chipped and with gas prices being so high, any extra is a Godsend.Perhaps a better question is who would buy a chip for a naturally-aspirated engine?

Jeff, the reason they shelved the project is a lack of interest from W8 owners. Jeremy over at Matrix Integrated was taking deposits for the intake last year but it didn't generate enough folks to merit further development or manufacturing. Unless you can get about 10 other W8 owners to financially commit to purchasing an intake, it might be a moot point.i am running the wett chip when kelly was selling them I think i got mine for like $300 after mentioning clubb5.
I know that GIAC makes chips for 6-speed and tip
also... does anyone know anything more about the matrix intake for the w8, i know that they produced a prototype but stopped at that for awhile because of other projects. Does anyone have a relationship with them to e-mail them seriously. I don't think that an e-mail from someone they dont know talking about a 3 year old, shelfed project will do anything. Thanks
