Chipped cars ONLY! - 986 Forum - The Community for Porsche Boxster & Cayman Owners

I think we all know that there are a lot of people who think that after market chips do nothing for a cars performance. This thread is not for them. I am interested to know what chips people are using, if they are satisfied with them, if they feel that they are worth it and also if they have also done the intake/exhaust mod with it. I am considering a Revo chip with the SPS 2 option as it will let me switch between 91 and 93 octane fuel. I would love to hear others opinions especially if you have had experience with GIAC or REVO.

Hi der Geist, I don't want to hijack this thread or take it Off Topic, so I'll delet this if you want just, send me a PM. But I have a question. Is there really a big difference between 91 and 93 octane (2.2%)? Thanks.

Not all all, I think that is what a discussion board is all about. Like most mods in everyday driving you are right-there is really not a whole lot of difference. I doubt if most people would even notice it. My past cars have always seemed to run just a bit better and cleaner on 93 and the Boxster in particular seems to run smoother. Like all mods though I think it will only make a difference under extreme circumstances such as REALLY spirited driving or track/autocrosses. You mentioned 2.2%. My last boss (and mentor) once asked me if I knew the difference between a race horse that won a million dollars a year and one that only won one hundred thousand dollars a year. I thought about it for a second and admitted I did not know. He told me the difference was 1%. I asked how that could be and he replied "because that's all it need to be-just a nose, 1%. So while I know I won't be blowing away any 987 S's, chasing Carreras down the back straights and I will watch Corvettes tail lights pulling away from me at a speed which I could never match I believe that all these 1 & 2 percents add up and can result in a much better driving experience. Not only that but if I come across an unsuspecting 986 I can smoke him!

Just my .02 or was that .08?? Sorry for the long reply!!

I think there may be someone else out there who may have a better understanding of the differences and might explain it more clearly. Anyone???

Here is the dyno run for an '03 base Boxster after exhaust, intake and Revo chip. This is at the rear wheels so HP at the flywheel should be substantially more. All I know is that the butt dyno says "HELL YEAH!!" I didn't get a base dyno from bone stock so if anyone out there ha one for an '03 2.7 I would appreciate you posting it so we can all see the difference and see how HP to $$$ these mods really are.

Hey der Geist, I don't have a '03 2.7, but mine is a '02 2.7, which should be a little less powerful than the '03 based on Porsche's factory ratings for the change in that year.

Here is my baseline dyno. My only mod included is a "desnorkling".

For what it's worth my local Porsche tuner race shop will do a free 5 hour REVO flash to see if you like it before paying for it. I'm sure any REVO dealer will do this. I guess REVO is so confident about their product that they allow for this free trial. But I've also heard that GIAC ? Makes a better performance chip. I haven't researched them yet so I can't say which is better.
