I put supra 315cc injectors for my turbo set up. In neutral I can rev it to whatever but when I take off in first and get ~4.6k rpms it boggs down like its loading up. It does it in every gear 1st-5th. I need help into resolving the problem.
Thanks in advances and is there any post about egr dels on 7a engines? -Matt! --------------------  |

if your running the factory ecu then your most likely running WAY RICH, those injectors are way to big for the stock ecu. can you give some more info on your setup?

without something to tune them, you will run wayy too rich
the 7a switches to openloop about 4.5, and the afr drops from 15 or so to 11-12.5, so at that switchpoint you may go so rich you dont produce power atleast thats what my 100% stock 7a does w/ a wideband hooked up -------------------- QUOTE "And, as always, your friendship, help, and dedication to the advancement of Texas Celica dominance is GREATLY appreciated.
