I have a 1998 c5 a4 has any one tried the hypertech programmer on their car that can tell me if this is worth the money and can I expect any could gain? Also has anyone ever seen a horepower claim by installing this in the car?

 

Dwayne, if your C5 is relatively stock, you might see a tenth at the 1/4 mile with the HPP3. Look around and you will see a LOT of people selling their used HPP3 because LS1-EDIT has become available.

Most of the people who bought Hypertech's were just so that they could change things like gear ratio, rev limiter, etc - not for any real performance gain. In fact my car seemed to run worse with either the RFG or non-RFG tuning.

What was the air/fuel ratio on your dyno test
for the HPP3?
I just bought one for a gear and rev limiter
and I am going to test it on the Dyno when my
clutch gets broken in.
I just want a little heads up.
Thanks
