I will say this...I've read people say it only gave me a 2-4 rhp gain, basically a wash. In fact, that would be about the going rate for increase in horsepower. About $80-100 bucks per horsepower. So in essence, you got what you paid for. Being it cost 4500 to 5000 for a supercharger that may give you 35-50 hp gain. You do the numbers. Just my humble opinion.
I don't know of any superchargers giving "just" 35-50 h.p.. It's more like 100 h.p. +.
Will it give you a lot of HP, no, but will any tunning without a dyno? Will anything for under $300?
It works for me, and I also had better track results with it, and up to 2 MPH faster. When I took it off, I tried and tried, and my MPH was always down, and up to 1.5 tenths as well. Listen to people that have used and tested it at a TRACK, where it matters. I think you will find good results, and only a few that are not happy with it, others are just expecting too much I think.
I recommend it for the A4. These are all the things I have done with results.
Shift points and rev limiter increase do work.
Increased the firm shifts by 50%
I also used it to change my gears to 3:42 (no problem, not sure why others only go up to 3:15, maybe a 1997 car, or older hypertech issue)
Removed the Speed limiter (sets it to 255MPH)
Tire Height
Fan On Sooner for Hot Summers
I think if you have an A4, it is a very good mod.. I got 4 tenths from the thing, just from the shift points, rev limiter setting, and fan control setting. I am also one of the few 2.73 geared cars that can regularly get into the 12's without any motor, tranny, or gear work (few boltons listed in sig). If you know where to set the shift points, it can make a real difference. The power programming i will agree doesnt do much. These are just my .02 cents worth, hope this helps..
Hey guys, thanks a million for all the responses. I have a couple of additional questions. Can you adjust the shift firmness only, without doing anything else? And can you adjust the degrees of firmnes? I would like the car to bark the 1st 2nd shift without loosening the fillings in my teeth on normal partial throttle driving.
Thanks again! :chevy
Curt you can change the shift firmness only if that is what you want to do. You can do 25, 50, 75 or 100% if I recall correctly. However, the shift firmness swith is at all throttles for all shifts. So I had it set to 75% and in the morning when pulling out of garage softly I get yanked. If you switch the prgram back and forth for what you are doing then that will work but if you leave it you will get a firm shift all the time.
Thanks a lot RedGar. Does the programmer do something with the torque converter lock up as well? Sorry to be a pain in the as here but I am trying to learn about this new device from scratch. Trying to learn all about HP parts out of a Mid America catalogue can drive you :crazy:
Hell I bought mine just to change the rear end ratios only to find out I couldn't. Programmer for 97 only offers 273 and 315 rear ends so hypertech was useless to me. I called and bitched that they should have pointed this out somewhere so I would have known before I bought it, they told me tough break and no we can't give you your money back. Anyone interested in one for a 97 make me an offer.
Did you purchase with a credit card? I would have done a dispute on that one! Even if you lost - and I think you'd have had a fair chance - you would at least tie their (your) money up for a while. And I'd file complaints with the BBB and the credit card company too.
For an A4, you may want to consider the Predator. There are several threads running with all the particulars. I have one and have documented dyno gains. Track times will be coming soon.
Basically, you get all the functions of the Hypertech, timing and a/f adjustments (very important), more flexibility, and a built in scan tool. I would say it is a step up from the hypertech, but not an LS1edit type of tool. Do some research or ask some forum members that have one. Just an option for you. :cheers:
First, I don't race my car and its never been on a dyno (yet). Strictly SOTP here. Also, I bought my HPP3 used for $150 so that makes it much easier to swallow! You can take what I have to say for whatever its worth. :)
Installed in conjunction with a 160 stat and I set the fans to come on sooner. I noticed snappier and firmer shifts and my car runs much cooler too. Did it make any more HP or would it have cut 10ths of my ET? I'm not sure. But for the price I paid, I'm satisfied with the noticeable SOTP differences. :cool: :cheers:

Where did you have your shifts set ? I am currently playing around with mine I think I am at +3 on the 1-2 and +2 on the 3-4 I rev limiter 6500. I think I need to up the 2-3 shift as it is only maybe around 5900 or so.
+2 on the 1-2 shift put me just slightly over 6000 rpm. +5 on the 2-3 shift puts me slightly under 6000 rpm (I will probably go to +6 in the Spring). That combined with lower fan turn-on settings, 75% shift firmness and a 6300 rpm rev limiter (the car would sometimes hit the stock 6200 limiter when it broke the tires loose on shifts) really did the trick for me. I also downloaded the power programming...don't know for sure if it helped, but didn't get any pinging, so I left it in. The car runs very strong and really well with the above. Is the Hypertech worth it? To me, absolutely! :yesnod:
Ok, I decided to bite the bullet and ordered the programmer today. Based on what you have all posted, if I get no more than a good crisp tire barking shift out of the divice it will be worth the money to me. I am not going to download the power program in order to make sure I don't have excess spark knock. Thanks for the info.
I went +3 on the 1-2, wanted to push it, I also upped my rev limiter to 6500 to make sure I dont bounce off it as that will rob power. My 2-3 is only at +2 I think now I am going to try and up it to +5 one day this week. The 3-4 happens so far up I didn't bother with adjusting it. :seeya
My 1-2 I think happens around 6100 the 2-3 is more like 5900 hence my desire to up it. :chevy
Now you've got me thinking about trying to change shift points afterall...in your post you say +2 for 1-2 & +5 for 2-3...has worked for you
Have you done anything for 3-4?
I'd appreciate your thoughts & experience :yesnod:
Dave, that 3-4 shift occurs about 145 mph, or so, and I don't spend a lot of time up there so I did not adjust that shift point. :D Let me tell you what the Hypertech really cured for me. I used to really have issues when punching the car at 30-35 mph and 70-75 mph. The car would not always downshift as far as it should have each time. It would vary. I discovered that this is a normal occurance on an A4 as many parameters are looked at when the computer selects which gear to drop down to. Adjusting those shift points has eliminated that problem for me. Now, when I tromp it at those speeds it always drops down to the lower gear which really makes the car haul azz. Also, when it does shift, you are much higher in the power band of the next gear. This thing works for an A4. Concerning M6s, the same as the Powerloader, or Predator also it now appears, I don't believe there's a lot of performance value.
