Just installed a set of 24lb injectors and a 24lb injector calibration tube for my mass air. I immediately could tell a difference in idle. Before it would idle good with minimal surge but also had about a 12 on my voltometer. Now my voltometer is 13-14 with better throttle response. Is there anything that would need to be done with this change? I do not have the cash for a dyno tune. Anything to check to make sure fuel air is good? Any pointers would be appreciated.

Look into the Apexi SAFC. It is a low budget air/fuel controller, and works great.
Do you have a scan gauge?

I don't have a scan gauge. I would possibly be interested in a air/fuel gauge. Are they hard to install? I know there are a ton of guys on here that can really tune without a dyno. I may just have to play with my fuel pressure at the track. Any help on tuning would be appreciated. Actually is there really anything to tune? Doesn't the computer take care of the air fuel ratio. I mean that is what the calbration tube for my mass air is for, right? Or does stepping up they injectors not allow the computer to work the best since it may still think I only have 19lb injectors? Any info on how all this works would be nice. Thanks!

Since you installed the calibration tube you should be fine.

just leave it as it is, until you CAN afford a dyno tune
