So, I keep on looking at The Wizard's dyno chart and it makes me want to skip out on getting a JWT ECU and 370cc injectors.

Before the EU, his A/F would get pretty lean up top with a MEVI, Vortech T-Rex & 8:1 FMU, and stock injectors. If I were to go with a similar setup, but with 290cc injectors and an 00VI, do you all think that the slightly larger injectors would give me a slightly safer A/F? Would I be able to run A33B 315cc injectors w/ the stock ecu, or would I have idling problems?

I understand that other mods/factors may give me different results, but I figured I'd throw the question out to see if other guys running similar setups (stock ECU) could chime in. I would be running a 3.125 in. pulley on a V1, btw, hence the ~10.5 PSI.

Here is his dyno graph (hope you don't mind me using this, James):

 

Just for clarification, I'd like to make a few corrections/comments.

1. I didn't have a MEVI back then with the dyno you're showing, just the USIM
2. I didn't have a test pipe installed, so my readings are a little leaner than what they actually are. Cattman Fastcat in place. A/F was taken with a tailpipe sniffer.

No problem on using my graph. Glad you found it useful.

Now, with this Dyno.......
The MEVI was installed, and activating at 5200 rpms
Cattman ceramic coated headers were installed (took off Cattman ypipe)
Test pipe in place. A/F was taken with a tailpipe sniffer.

Further discussion to follow.....

 

Those AFRs up top look deadly..
