Wait 58lb SRT injectors? From the Neon SRT4, I hope? Stage 1? If your running SRT8 injectors, they aren't 58lbs, not even close.

Those are the same ones I'm on running on my heads/cam truck. They're fine. If I did my math right they should be good for close to 800hp.

Where are you located? Theres nobody better at tuning Hemis then AJ at Westbury Jeep. If you're within a 500 mile radius of NYC, I'd definetly suggest going to him.

we got the afr down to 12.6:1 wich is better than 15:1 but its still too lean after 4500rpm but were getting closer.
