Came across this video on Youtube from a shop called Autodynamica that claims 410hp with Exhaust, Software and Intake and cat by pass pipes.

I've only been looking at performance mods for a little over a week but all the sites I've been to advertise maybe ~52hp at best with these mods. I went to that vendors web site and they don't even have a stage 1 package like in the video. What do you guys think about their 410hp claim? Possible with those mods?

 

I don;t know the answer. I just got my '05 S and am reading up on performance mods. InMotionUSA.com has a Stage 2 ECU reprogram to get up to 370hp (+30hp). Will performance mods void the factory warranty??

 

Okay, maybe its just me but something about that site doesn't seem credible. And am I reading it right, their stage 2 ecu upgrade is only $300 for th S? They don't even have dyno sheets. I'll believe it when I see it.

 

a good friend of mine just got the ecu upgrade for his turbo 996 and is very satisifed. i'm a newbie so it's all greek to me. what's the difference stage 1 or stage 2?

 

The only other ECU upgrade I've come across is from GIAC and only adds about 12-15hp. It also costs over $1000. You can find it here.

 

Oh and if this InMotion upgrade is for real and really does add 30hp then I think you may have found a real gem!

 

send a pm to 'colorinc' and he'll give you a 1st person testimonial.

No, it's not possible to get 70hp with just these mods. Based on my experience, the only thing that can give you an extra 70hp on a normally aspirated car is NOS, turbo add-on, or major engine work (higher compression pistons, head work, cams, etc.).
