What year, intake, and size injectors would be helpful.

Actually list all your mods and I will make a starter bin for you.

Thank you

Intake: stock not ported
cam: lpe 211/219
rockers: 1 to six giving 530 560 lift
compression is about 9:7:1
ignition: dui distributor
exhaust: tpis headers with cat
injectors: think they are Bosch threes from John at FIC
torque converter : Yank 2800 locking converter

I purchased the Ostrich 2 to interface with the computer

The car runs and start just fine. It will surge a little at idle and at 55 in od the car will buck a little. It seems to run rich

Okay I found the receipt. The description says that they are bosch des 3 with dia therm. No mention of the flow rate but I believe I remember them being 24lb injectors.

I attached the starter tune and the original text file of the stock tune and the txt file of the starter tune, you can print them and compare the differences so you know what i changed.
