Well there's a huge price difference Wester's being $295 and Fastchip being $159 (??)

Think they actually make that much more power? I just got done reading that other 14 page thread on westers, and it seems messing with a/f ratio doesn't help all too much on these cars, so basically we're gaining from timing advance.

Thoughts?

I can't say if Westers chip makes more power. What I do know is that if it does, it must be more timing and the higher risk of engine damage. I also know that Westers alters the transmission control side of the chip. The chip is actually called a dual mem-cal. It has two proms/chips. One for engine control, one for transaxle control. Fastchips doesn't mess with the trans control, which I like as my trans shifts fine stock. I don't want "firmer" shifts. Especially since it does that already when you put the shifter in 2. I've had my Fastchip in for 2 months. It makes more power low end & midrange and the speed limiter is gone. $159 vs $395......:thepan:

And the Westers chip is $395, not $295. Click on the link, it's the third one down.

Opps typo on my part.

I wondered what they meant by dual memcal. Now I know. I agree, my trans shifts solid if you put it in manual 1 or 2. Squaks those 18" wheels/tires. :thumbsup:

I highly recommend the fastchip too. The price is right, and while the power gain isn't anything all that noticeable, the speed limiter removal is freaking sweet.

Well I"m not too worried about the speed limiter, I haven't even found mine yet in the STS. :)

I'd hope the power is noticable though, is it really not noticable?

As I said before, definitly more power at low end and midrange. The 12 to 15 hp they claim is accurate. I switched the chips back and forth to be sure. Also, 93-95 STS and ETC don't have the speed limiter.

Maybe I'm just so used to it now I don't notice the difference. :thumbsup:

In fact it should give 10% increase in HP .I remember when my 'lade was reprogrammed those guys told me like that .
In Northstar perspective, I think, it can even hit 330 HP afterwards

Where can i get the fastchip? Fastchip.com i am guessing. Any one know if one is made for for a 96 sts?

10% is rather optimistic, for a chip. You're not getting any more air into the engine, which is an air pump. All a chip can do is play with fuel and spark mapping. Cadillac wouldn't have left 10% on the table if it were safe. If a chip maker is getting 30 horses with just fuel and spark mapping, there's a huge compromise elsewhere. Hopefully it's not in durability.

There are no chips for 96+ vehicles. They are OBD-II and the computers are much harder to reprogram. Check the thread re: Westers Hacking the Northstar or whatever it's called. They're trying to work on a way to re-tune an ODB-II Northstar.
