obviously the guy didn't know any better or he wouldn't be asking questions. How many of you have fucked something up when you DID know better. Give the guy a break............

 

But don’t you have the tune off the 5.3 that you blew? Did you had those injectors yet?

 

So you are going to tell him to drive it with the smaller injectors, and not give it too much throttle? Are you sure you want to do that?

 

well im still running my 5.3 tune with with my new engine, and yes i already had this 60# injectors when i got it tune with the old 5.3L. My tuner said it shouldn't of changed much after the 370 6.0 forged and before it would run great with 5.3 even tho it only lasted about 1 or two hours after i got it tunned. So after i installed and upgraded to a T76gts turbo on my truck it started to do this kind of problems it turns on good its just when i drive it around the block to test it with just a little gas about 1/4 to 1/2 of throttle it starts messing up i cant just hit the gas full throttle cause it just wont go. like if the air/fuel isn't tunned right, well i don't im taking it back to the tuner so he can fix the problems... this Saturday im going to take it to my tuner so he can do a SD tune with a 2bar and see how it works out.

 

So wait I am confused, is it tuned for the turbo or not?

 

yes for the turbo... when i had the 5.3l with the turbo (mpT70) and then i blew it up and so now i have a 6.0 forged 370ci. and now the problems are here.... and it wasn't even wide band with the 5.3l turbocharged, thats the way my tuner did it he was going to to tuned it the next day which was Saturday dyno tuned but on my way back home i blew my 5.3 engine and ever since i swapped the 6.0 i just took it back for a little tunning out side his shop and i just haven't had a chance for a really good tune, we will see this Saturday when he dose a SD tune if my problem get fixed or not...........

 

Yeah your tune is probably off some, The pics of the plugs actually looked good to me . you want them to be a light brown, not white or black. Its pretty hard to check how rich or lean ou are running without out shutting the motor down immediately and pulling the plugs. Get a WB than you can really see what is going on.
