In 944 spec we used to run off the shelf chips. However the rules took all chips away due to some custom jobs. Those of us that pulled the off the shelf aftermarket ones have noticed not change in lap times as a result.
any chip designed specifically for an NA 944 that netted +22/26 HP/TQ would be worth A LOT more than $25....
furthermore, raising a rev limit wont really "broaden" the powerband...the 944 band is only so wide (due to cam profile and head design), between about 3000-5500rpm, so setting the rev limit to ~7000 on an otherwise stock engine wont do anything.
also, big clue should be this statement:
The top speed governor has also been eliminated, enabling the vehicle to achieve it's "natural" top speed.
the 944 has no top speed governor. it is drag limited to its top speed of ~140.
go ahead and try it if you want, its just extremely unlikely that it will work. be sure to use premium fuel when you put the chip in as many chips are programmed for more power by advancing spark further than stock which with the wrong fuel can make things go boooooooooooooooom
I've always run premium fuel in my 944's of past and this one too....course its just a play toy so I'm not dumping as much fuel in the car as some of you might be....
Do these cars run 87 octane from the factory?
if you look under the gas cap it should say "min. oktan RON+MON/2 = 86" so yes, 87 is perfectly fine. i too ran premium for the first 2 years of ownership before realizing i wasnt doing anything but propping up an oil company.

I now have a MAXHP chip, also GREAT!!!
just to clarify, im not discounting chips for 944s entirely (although the few that ive seen have had little gains), just the one that was posted on ebay for $30.
Yes, the 83-87 cars can 87 pump gas. In 88 they upped the compression ratio so only run 91 in these cars. I run 91 in my 944 spec race car.
Let me tell you that putting a chip you will be luckey to see 2 hp and will NEVER SEE 20 hp. It just won't happen. You will hear a slightly different sound on full throttle and gas milage will decrease. However actual power output will not change. We have had cars on the dyno and can detect a very small change there (2-3hp range), but even on race track we can't see the difference in lap times. It is waste of time and money. Now if yout take the car to a dyno operator who knows 944 tuning and have him create a custom map for your motor you might see some gains. May 5-10 hp in the mid range and 2 peak hp gained. However I would expect it to cost you $1000 or more due mostly to the 8 hours of dyno time. That is only if you can find the guy with knowledge to do that and have a few other motor mods that the chip can try to take advantage of.
