I just checked the chip in my 84 T Type and found it is the Hypertech 424 012. I have seen some negative comments about this chip. How does it differ from the stock chip? I looked on their web site and they still sell this chip but don't list any information on it.
Thanks. I will look for it. I am new to turbo buick's and bought this car as a project. I have no history on the engine except that the PO said it was rebuilt and it is painted a different color than stock. It runs fine at part throttle and idles well. I think I have a long list of things to look into. Should I switch to a stock chip to establish a base line?
Impossible to answer until you know exactly what condition everything is in, and what the combination of parts is. You also need data to make the right decisions. Post your location and see if someone will look it over for a few beers.
Good idea. I am in Reston Virginia outside of Washington DC. Anyone in the area that can offer me some help would be appreciated. I would also like any suggestions on a shop in the area that works on these cars.
