Just did some major upgrades to my 89 GTA this summer ( HEads, Cam, Intake, injectors)and am looking for someone to help with my final tuning. I have searched the internet and have made some phone calls, but I can't find anyone with a dyno that is willing to tune thirdgen cars. Does anyone know of anyone or anyplace here in the midwest that will do this. I am located in S.E. Iowa.

There is two places that i know who are really good with third gen tuning. One in Madison WI, and one in Chaska MN. I have gone to both and would highly recommend. Any questions just ask

I just did a load of work to my 91 Z28 as well. Its a 305 but all this will pertain to you as well.
If you havent done it yet, put it on the scanner and get the following numbers and specs:
1. MAP Vacuum......get reading as running at park idle and driving and it needs to be in Metric KPA
2. BLM #
3 Have all your engine mod specs: heads, Cam (which you will need to know ACTUAL lift, duration, and LSA) the manufacturer will have these numbers for you. Know what your rockers are, size of injectors, any crank changes, transmission modifications, and rear diff gear ratio.

When you have all this........CALL BRIAN HARRIS at Harris Performance (aka TPIChips.com) and he can program your car to run like a dream!!! His number is 336-471-2827.
