NEW, Stage 3 chips.
I have added the stage 3 as a slightly reduced price of custom chip although there is still a lot of custom stuff that needs to be done. This chip is to delete codes for things like IAC valve, o2 sensor and knock sensor, to pretty much have TBI run the ignition timing on distributor and shift the transmission or on the older models, to lock the tcc just like it came that way. The reason I have added this is throttle bodies are becoming obsolete. The injectors are hard to find good ones and the units themselves do not flow enough air and the computers are too old and slow to control the fuel very well with more aggressive camshafts. With systems such as Killshot Fusion (Flash Sale) which as of this writting is only $500. You do need fuel pump upgrade which needs to happen regardless of what upgrade you do and AC DELCO which I recommend a lot as it just plugs into the stock fuel sending unit for least amount of hassle. you will need to plumb in an external fuel pressure regulator and Aces can likely help you with what works well. This chip will take care of the timing and you will feed tach signal from the white wire on the gray plug of ignition coil to ace system. use a TPS Y adapter off Ebay to split TPS signal for TBI computer and aces. run coolant temp sensor for TBI and just add the aces sensor to port on passenger side head. TBI will need map input so hook its vacuum to the ace throttle body. for ace power the key on power you can use from the old TBI injector wiring and battery from block on firewall. leave the rest alone. I believe this will be the most popular chip pretty soon as that aftermarket injection can learn the fuel for the new engine setups and allow for a much more aggressive engine setup.
