Hi everyone, just finished rebuilding the engine on my 84. Literally everything is new except the block: heads, renegade intake, headers, all new internals. It's making a lot more hp now, but running lean. I am wondering if anyone has had their 84 TBI's bored out, and by who? I sent mine to Dr. Injector in Washington. He did nothing with mine and I almost had to sue to get my money back. Complete scam artist. Who have you used? Also are there any larger injectors that are a direct fit for the 84? I already upgraded to the 85 fuel pump. Please help with any TBI recommendations at all. And I want to keep it a Cross Fire. That's what makes it unique! Thanks in advance.

I have a Hypertech Performance chip Stage 2 for an 84 Corvette . I want $60 shipped for it. This did make the car faster. Let me know if you want it. Paypal ready.

A throttle body bore allows air.....if it is running lean, you don't need any more air...you need more fuel.
A larger injector increases fuel (so does a correctly working injector).
 
What makes you think it is running lean?
 
Have you rebuilt the injector?

Thumbs Up   I agree.

Have you had the car on a dyno?   Can you post results?   What is your fuel pressure at full throttle?
