how to change injector size

[fxbdydriver]

I am a total newbie,
Just bought hp tuners and trying to learn. My lq4 with cam has a mail order tune and running well. I would like to swap out stock 28 lb injectors to use on another build. I am planning on going turbo so I would like to go ahead and put 80 lbs in. Can I swap with simple adjustment without having a major re-tune?

Thanks,
Josh

especially on the older PCM's you really need to have the correct data or you will have a hard time tuning it.

if i were you i would go for ID850cc as there is data available and your car will be smooth

I was planning on using Siemens deka 80's. I was hoping there was a table or something I could adjust to let Pcm know I have 80's??

Can I just open hpt files of gen3 tunes that use same injectors and plug in the correct data?

i dont believe you will find deka 80's.

He meant you won't find good HPT plug and play data for them
