tuning a boosted 09 chllenger

[J-Z]

Why is it so hard to tune a boosted 09 challenger with 11 psi. My tuner has dyno tuned lots and lots of cars just not the 09 chally. we cant get below a 15:1 afr.

Has he contacted us for help?

have you upgraded the fuel system?

[J-Z]

I have a kb bap and 58lbs str injecters. Yes he has and cant get anywere. I dont know why but its drivn me nutts not being able to go into boost.lol

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

[J-Z]

sorry, yeah srt4 .Andy at pwr said there thr same injecters that he had on a supercharged 426 so they should flow more than enough.
here's the number on the injecters
04891574ad
9077x09406

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.

So its gota be tuning issue but it seems that every bodys tight lipped when it comes to helping tune these cars.

[Mike_Levy]

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.

[J-Z]

Im in seatle Mike. the cars going back in tomarro,hopefully hell get some help from diablosport.

[mikel]

Your tuner does have CMR, correct?
Hes not just trying to do this with the Predator, is he?

[J-Z]

Hey but the mustang is a WAY BETTER CAR.

[J-Z]

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.
