I would recommend cleaning the radiator first. If you have to spend money, buy the chip first. You may be very surprised at how effective the stock cooling system can be with a clean radiator and a good chip. My ZR1 would always overheat when I got it. I cleaned the radiator and the car would run just under the hot mark with a GM chip. With a haibec chip the temp never even reaches the middle of the gauge. I was most impressed.

One thing that did not seem to make any difference on my car was a lowewr temp thermostat. I think I have a 190 or 180 in it now and I never noticed a difference from the stock piece. Goodluck with the cooling.
