Any experiences with Hypertech Street Runner?
I have an 86 coupe with 4+3 transmission, K&N air filter with open faceplate on it, otherwisw pretty stock. OD works fine. On Interstate trips I get 22-23 mpg by calculation (the digital dash agrees very closely with those mpg results, but I would like to get better mpg on the open road.
The Hyperchip Street Runner sounds/looks like a nice insert for me, but the hp chart on the Hyperchip website doesn't look like it makes much difference below 3500 rpms. I am turning 2000 rpms at 72 mph on the Interstate, and I'm rarely above 3500 rpms, so I wonder:
Would the Street Runner chip make any difference for me in mpg or general driving?
I did a search for Hyperchip, and only hit 4 results. In one reply I read a comment about 22-23 mpg might mean an O2 sensor is faulty. Does anybody have experence with this?
Thanks for the feedback.

When I was running higher fuel pressure with my AFPR, an agressive TPS setup, base timing bumped to 8deg BTDC and a 160deg T-stat & fan switch, I tried a Hyper Tech chip and saw absolutely no difference at the strip nor on the highway.
I don't think that chip will add anything to performance nor to gas mileage.
Have you checked mileage averaged over a few miles of flat highway with cruize set?? These are the conditions under which I feel that I can get reliable readings for comparison with each mod I make.

you should be getting closer to 28+ mpg on the highway.it may be time for a full tuneup if that has not ben done in a long time,also dont forget to change the fuel filter and i would be suspecious about the 02 sensor,they are not that expensive to replace on your year.

Chip is useless in terms of mpg and HP.
First thing to do is give it a full tune-up, plugs/wires/cap/rotor, then O2 sensor, and then you may need to replace injectors because if one is leaking it'll kill your mileage.
