Hey guys.
I finally got my 69 camaro out and get it running and dyno tune. After paying arm and a legs. I still find that it could be better.
I notice when it start up. is a bit rich. by looking at the LTFT and STFT. I am staying from 0 on LTFT and -3 to -8 on STFT.
I also notice it seem to bog out at a mid RPM. Is the timing correct? I do have a mild cam on the car.
Here are my motor list.
-LQ4 6.0L
-L92 heads with corvette yellow spring.
-LS3 intake manifold and LS3 stock injector
-Comp XFI RPM Hi-Lift, XR275HR. Part #54-426-11 222/224 .566/.568 112.
-90mm elderbrok throttle body.
-stock Mass airflow
Please have a look at my file. If you can make some changes to help with the mid power would be great.
Eric
