advice on tbi setup..

[bdads]

hey guys,,,
wondering if someone can give me some advice on tbi tuning chip wise for a 1992 firebird,
the car was a 305 tbi setup--- I was going to change it to tpi because I have a complete set up off an 1989...
then I changed my mind to save the tpi for another build---

here's the basics--

I have moates equipment and have used it to tune my 377 stroker with tpi--
it runs great and is consistant--- it took a bit to get used to it-- but overall I am comfortable with the chip programing and basics----

can I take a worked up 355 with good heads and 280's or so cam and get the stock tbi to flow/work good for it ???
I'm needing to be around 5500 rpms 6000 max-----

with this being a different ecm-- is there a zif socket for this style chip???? or whats the best way to work with it ???

any advice is much appreciated ,,, thanks- steve:rockon:

Have you looked at the TBI update thread at Thridgen.org?

If you decide to update the computer, include a Wide Band Oxygen Sensor (WBO2) in your parts list. More information on WBO2 tuning: http://www.gearhead-efi.com/Fuel-Injection/showthread.php?5381-Wide-Band-O2-(WBO2-Tuning)-Spreadsheet

Basically, the TBI would work but you will need to make changes to support the fuel required and you might want to change to a larger bore TBI to get more airflow.

is it still common to work with the 454 tbi ??? sadly this unit is on a shoe string budget !!!!

One of the EFI Rules:
The more you know about EFI, the less you Pay for EFI.

Another EFI Rule:
The more you know about EFI, the better you can GOOOOOOOO with EFI.

Sure a 454 TBI can work, if you do your homework.
