1958.

Take a look at the link kinda cool.

Actually Boseman is right. The DHP pcm does add horsepower besides the shifting and governor. It also kicks the fan on at 180. I have been talking to Dave who has the beta version in his 96 SSEi and he said it feels strong but he hasn't taken it to the track or dyno yet. Most dynos have shown on GTP'* to be around 20 - 25 horsepower and it adds fuel to keep KR down so it runs slightly richer. Nobody on ClubGP has yet that I have seen been disappointed. They all say it is really strong around 4000 rpm and that it is very noticeable in all gears. Soon as they come out I will be purchasing them. Not sure when the N/A chips for Bonneville'* will be coming out but I was told August for the */C pcm.

The shift setting was an option but I am not sure when it first came out. I know my car has the perf shift button.

Hit 128 (210 kph) in my 2000 SSEi and watched as my buddy in his Ford Taurus pulled ahead. His Taurus doesn't have a limiter and will physically limit out at 141 mph.
I know my Bonne could do 150. It was smooth.
It won't be long, I'll be in touch with ASE chips. It'll be worth it not just for the 9 hp increase claimed, but getting rid of the damned limiters.....especially the one that limits 3rd gear to 108 mph!!!!!!!!!
I think the speedometer on this car is WAY COOL. The needle changes between MPH and KPH so you either have a 0-220 kph or a 0-220 mph gauge

Is there an advantage to relocate the AIT sensor to the other side of the filter where the cool air is drawn in through the fender hole?

I've added a 3.4 pulley, trans oil cooler, Casper hi-speed fan switch, heat shield and K&N filter.

Yes, locating the IAT as close to the filter as possible will deliver more power since the computer reads colder air which thus injects more fuel and the more fuel you can burn w/ the air then the more power you can make. Also fuel cools the engine a little more.

I still don't understand. Moving the AIT away from the throttle body to a cooler location tricks the computer that the air is colder than it really is so it adds more fuel.......hmmm.

The factory settings are on the rich side and the aftermarket ECM usually modifies these settings to run a little leaner.

So won't running richer just waste gas?

Besides, I don't think that the air temp will be significantly different a foot away. Or do you move it further than that? Like in the fenderwell opening?

it will make a difference....

i noticed a little power increase just by removing my TB screen....

I have a '93 SLE (N/A). You guy probably know that this means a gearing of 3.06 instead of 2.73 (that'* what I'm told). Anyway from what I've read, the SLE'* (N/A) had been tested and the top speed was found to be 136. That makes sense since I have 225/60HR-16.

Best speed so far...115MPH in my 92 SE! BTW: that was with a tail wind but who'* counting!

Had my '95 SSE up to 112 MPH on the HUD last summer on a straight flat country road. Not sure what its goverened at and I wasn't pushing it any further because I was running out of road I'll have to try again this summer on a longer road and see what she stops at.

Depending on the slope of the road, tail wind, passenger weight, etc..., I have had mine top at 112 (with passengers) to 115 (empty). I am running a fairly stock '95 SSEi. When I hit the governor at 115 it hits hard. @ 115 I can maintain speed with only 3400 RPM and about 4 PSI for boost. I know it could do around 140+.

I know there was a reworked Bonneville SSEi ('94 or '95 I think) that hit aroun 202 mph on the Bonneville salt flats!
