510cc yellow tops Vs. 450cc stockers

[cbellsondsm]

i bought 510cc injectors from a guy for 100 i know the stockers are 450.... my question is 60cc doesnt seem like that much, whats the most i could do with them, ive got a 2 g maf and all the supportign fuel upgrades, and and afc 2, im not installing them until i get and idea if it is worth the time or not

Might as well if you have a safc... takes 10 mins tops to install injectors.

I used to run the JDM 510cc injectors with my 2G MAS, and I found that I was still running pretty lean (without an AFC at the time)... I got on average 120-130 on my L,M,H fuel trims... I was boosting up to 13-14psi before I got into knock, so I backed off the EBC and I got creative...

Having hacked my 1G MAS to schit before I installed my 2G MAS, I figured that the same "rule" of hacking the 1G would also apply to the 2G MAS, but in reverse. -I ended up blocking off the whole lower section of the 2G MAS, until I was able to install my SAFC. Once installed, I was taking away about 10-15% accross the board to help level out my fuel trims.

That worked for a while, but then I noticed that the ECU was adding too much timing as it was seeing less airflow via the SAFC, so I decided to get an EPROM upgrade... That solved my problems entirely and the SAFC had about 0% correction after that.

I have since then upgraded injectors as well as the 510/2G MAS EPROM... I still have it. -PM me if you are interested in it and if you have an EPROM ECU. You can see the ad here:

To see if your ECU has an EPROM, it should look EXACTLY like this:
