    Are you still using the original 1992 305 TPI computer?

    Perhaps you are up to the challenge of doing the chip yourself?

    Link of information for the stock computer you are using: http://www.gearhead-efi.com/Fuel-Inj...Information-8D

    There is some "Internet Hype" about custom chips, "tell us EVERYTHING you did to the engine" so we can sell you a chip. The Hype is simply that, Hype!

    Some helpful thoughts about building your own "Starter Chip".

    Start with a known good factory chip file, or .bin file. Verify the injector flow rate in the "Starter Chip" is correct. Remove unnecessary functions like VATS and / or Emissions. Find a factory ZZ4 camshaft timing table and adapt that timing table to the "Starter Chip". Perhaps a Factory LT4 timing table is close enough if you can find a ZZ4 camshaft timing table.

    The expense of your engine build is not the typical "Budget Build", so include a Wide Band Oxygen Sensor (WBO2) Gauge https://www.youtube.com/watch?v=qXqTxrzjwNA The WBO2 IS A MUST HAVE TOOL! Would anybody in there right mind using an Eagle rotating assembly not use a calibrated torque wrench? I would use a calibrated torque wrench even on a factory rotating assembly! Using WBO2 is the ONLY Way to accurately build, not buy a chip. Knowing the AFR is the only way go, when the challenge is FAST GOING!

    Myself and other members could help you with a "Good Guess" starter chip, likely as good as or better than the "Internet Hype" chips vendors. A good plan would be to take the chip building challenge yourself and let the members here help you along the way.

    One option to doing the chip yourself is to use an Ostrich 2.0 chip emulator so you can make chip changes even with the engine running. http://www.moates.net/ostrich-20-the...eed-p-169.html

    Using the Ostrich 2.0 allows members to post chip files / .bin files that you can download from gearhead then Upload into the Ostrich 2.0.

    The original TPI computer is still a very good computer. There is a TREMENDOUS amount of software and hardware support for the original TPI computer! Of all the OBD1 computers available, the 1227730 ECM is undoubtedly the most thoroughly "hacked" OBD1 ECM ever!! Virtually all the "hacked" 1227730 ECM information can be downloaded for FREE! The Ostrich 2.0 makes the original TPI computer FLASH, even with the engine Running!

    If you try the Ostrich 2.0 and later decide to move on to something else, the resale value / market for a good used Ostrich 2.0 is strong (about 75% of new)! Finding a used Ostrich 2.0 is not an easy find, it's a very good product.

    If you purchase an Ostrich 2.0, I'll provide you with FREE starter .bin file. If you shop the internet for a custom chip, you'll likely find the price of an Ostrich 2.0 is less $$$ than a custom chip!

    I think Not, the Ostrich 2.0 is for OBD1 vehicles (usually 1986 -1995), the 2000 Tahoe is OBD2.

    Hello Jim_Rockford,

    The Ostrich 2.0 will work with the 1227730 without a socket adapter.

    I could help you with a chip. I would use the Moates.net G1 adapter, with the chip installed into the adapter, see attached picture.

    Send me a Private Message (PM) if your interested in the details. It's likely the parts from Moates.net will get to Florida faster than I can get parts to you from Washington State.

    The G1 adapter can also be used with an Ostrich 2.0 chip emulator. (see picture below)
