have
Trans am 1970 swap ls2 6.0 with 243 heads ls1 intake and throttle cable 76mm
The engine work 8 piston afret 2 seconds work 6 or 5 and maybe 2 I don't know what problem in this engine the Rbm not stope in 550 it go up to 1500 and come down 750 not a good ls2 work the tuner tell me it have problem in fuel pump and inguctor it need 36 psi inguctor
What can i do help me ????

Anyone care to interpret?

I got nothing, almost understood it, but then got lost.

If I gather correctly, it initially runs on 8 cylinders, then it starts dropping down to 6 or 5 cylinders running. (how he'* able to determine this, I don't know)
Um, I guess it wont idle around 550, but fluctuates between 750 and 1500

And the person that tuned it for him is trying to pass the issue onto the owner.

And something about 36lb injectors. Don't these engines already have 36 lb injectors or bigger already?

Anyhoo Faisal1993, we really can't help with your situation due to the extreme fact that this is a huge engine swap project and we have no idea what kind of harness you are using, what the PCM is, or what year it is. And with us being primarily ENGLISH, we are having difficulty understanding you.
