ECU TUNING:- GIAC or EVOMSit?
 

Im thinking of getting it done. Which one should i go with?

I have the GIAC and have been satisified so far.

been thinking about doing this as well - what are peoples 'real world' experience with these?

rich

We are GIAC dealers and I personally deal with them allot! There company has fantastic customer service and they have always met our customers needs! Every time we flash a vehicle, our customer leaves with the biggest smile!

Let me know if I can help!

How often does GIAC update their software/maps? I have e-mail them several times never got a strait asnwer for my 2004 3.6l

Is this the same tuning for $1,000.00 and 10 hp?

This is why I'm currently toying with the idea of shelling out a couple hundred to INMOTION for their flash. I did a quite a few searches on this subject a couple days back because I was hoping to squeeze a few more horses out of my baby. Nothing I read was able to convince me that any of these flashes would be worth $1000 (quite the opposite most of the time)

I've read generally positive things about the inmotion flash, but I could never find a dyno graph showing any actual numbers.

I was thinking about offering the INMOTION guy $200 for his flash (he's got a $400 obo listing on ebay here

either that or saving up for a lwfw (which I've heard produces some of the most noticeable gains

Will you post back if he accepts the offer? I've had my car 2 weeks or so and I'm getting the itch for something.

Did you notice he has another auction for 369.00, same ad lower price.

Hate to keep editing, he spelled Boxster wrong. I hope he was referring to the motor design, doesn't look like it though.

I have a 99 like yourself and i did the GIAC flash a few years ago and boy does the car pull harder above 4500 rpm!! if you have a 99 your gonna feel the difference that's for sure...

and for all you other guys with 3.6 I highly recommend the GIAC flash cause another friend of mine with an 05 3.6 did it with TUBI exhaust and his top end power was improved...

but I will say this much... in many strait line tests his 05 3.6 could not pass my 99 with a GIAC flash and PSE exhaust... and we did many many roll ons... definitely worth the $$$ and GIAC is reputable.. they have been around...

Can you really feel 10 hp? Is your car a tip or 6 speed?

on a 99 because of Motronic 5.x vs the 01 and beyond Motronic 7.x ECU you will get about 15-20 hp and yes you will notice a difference above 4500 rpm and the dead spot that plagues the 3.4 engines @ 2900-3100 rpm is eliminated...

You will get more out of your flash if you have the exhaust modded to breath better.

Important Questions to Consider When Choosing Software
 

Zookie - Take a look at Softronic...all they do is the software..Though I haven't tried to others like GIAC, I can tell you that the Softronic can be done yourself and can be reserved at anytime (if you want to take to the dealer) with nobody ever knowing that you switched....

+1 on the EVOMSit as well;) Did a Cayenne TT today, a 997TT and 996C2 tomorrow and ever since we started using it we couldn't be happier. Support is great as well!

And the other cool thing is the 45-day money back offer they give with the flashes. Never had to use it but it's cool that the option is there and it speaks for itself:P
