i did this mod about a month or so ago. i got similar results. here's the link to my thread:

This is a really good product that delivers on it's promises.

 

Some had asked what rpm the max hp came in at, it was 5500rpm. I'm going to see if I can get a chart with rpm rather than speed. Stay tune. Oh the pull was in 4th gear.

 

Yet others still slam it for whatever reason.

 

its mostly from the guys that spent $17k (x51 kit) to get similar results. Id be PO'ed too...but then again wouldnt spend that much $$ for 25HP stinking HP.

 

But it's 25 PORSCHE hp, there's a difference, no?

 

25 German Horses = 50 American Limping Horses

This is True...

 

picking mine up tomorrow. can't wait!

 

how difficult?

 

How about a 6Speeder group buy?

It would go very nicely with my current mods.

 

That's next, I'll have pics and a dyno chart on that soon

 

you can see it on my chart that i linked if you can't get yours up.


With regards to the throttle body, i would probably shy away from that mod. i've talked to a couple tuners who would have been happy to sell it to me, but said that it was not worth the money. i wouldn't mess with the TB until I see some serious independent testing as the TB's are quite pricey.

 

I had spoken to Greg about this. He said he would do it if there was enough interest. I posted about it in a couple threads and it didn't really get much attention. I wouldn't expect a 30% discount or anything crazy like that though. If you guys can get enough people together I would be happy to set it up for you. Just find 10 people that were probably going to buy it either way and I'll try and get the best price for you. Bang for the buck it's probably one of the better mods out there.

I am almost tempted to go back and run my car again. We never even took my car off the dyno to do the install. Pretty much base run, install on the dyno, and the after run. We ran it up a couple times before the final runs, but I don't think that was nearly enough time for the ECU to adjust.

 

Hey thanks for the feed back. How much for the TB? I've been hearing $300-350.

 

Is this a larger size TB with larger butter-fly? Won't do any good to bore with out the butterfly.... I'm now going to do some reasarch into thing so I can see if it can be done, then it can be match-ported to produce more flow...
