Got in touch with EVO today and they told me the price for the GIAC program has come down to $795 from $1,195! Unfortunately, they don't have a program that caters for 98 Octane fuel

But they did claim that the ECU will automatically adjust to a more aggressive ignition timing to cater for higher octane fuel... But if that's the case, why bother with a re-program

Still trying to figure things out....

If they send it and you do not see the numbers thay claim with an EVO send it back, get the stock reflash and get your money back. Could be the best route to take.

Found this thread by chance while browsing through Renntech for instructions to remove my softtop : http://www.renntech.org/forums/index.php?showtopic=906

Much as I hate to, all this bhp/torque loss with the Evo intake may be due to a faulty MAF afterall

I'm still asking whether the dealership can tell reliably through their diagnostic equipment that my MAF is faulty rather than IMPLYING it's faulty because of a too rich air/fuel ratio. It'll probably cost me $1,000 to change the damn thing

Arrrgh!

While I'm on this, does anyone knows whether the S model uses the latest MAF model? Reason I'm asking if my car is already using the later model of MAF, I can just buy it off the web and replace the thing myself without having the dealership to re-program the DME to recognise the new model MAF. Will save me some money....

Did the routine 15k service today and asked OPC to run on a test on the MAF. Everything checked out fine. They're not able to tell the A/F ratio, just voltages from the MAF which was well within the specific range....

Over on ppbb a gentleman dyno'd his S after an Scargo and a GIAC ecu reflash. He netted like 13-14h.p. Not overwhelming but real. Perhaps you will see the same after the reflash.

I'm going the GIAC route with Evolution Motorsports. The program they've most closely matches the mods I've on my car (Dansk headers, high flow cats, muffler & Evo Highflow intake). The only exception is their program does not cater for high flow cats

Dynosports only has the one that caters for the Evo Highflow intake. I've a feeling that the program Evo has is proprietary to them as it's tuned by them. Someone let me know if it's otherwise.

Also, has anyone liaise with a particular person in Evo before and has positive experience? The 2 I spoke to over the phone were quite curt and not very helpful...

My car's in the paint shop so I thought I'll take advantage of this 'downtime'. There was another tuner in town (DMS, www.dmsautomotive.com) but they're from UK and charge GBP895 which is something like US$1,700 for a flash

GIAC's US$795 puts it at less than half price.

The usual dyno report will follow....

I wonder if the GIAC route would work on a stock setup... I would love to find a worthwhile mod (+10hp or so) that is <$1000 for a 2.7 Boxster. That plus a little meaner growl from the intake would make me happy as a clam. Mine is a weekend/fairweather car so I wouldn't mind if I had to always give it 94 octane and have it burn a little more fuel.
