1LW flash file

Hello all. I’ve been lurking here for a while but haven’t quite found the answer I need this time. A friend of mine has serial number 1LW10696. It’s current flash file is 192-5315. I believe it has 10R-0956’s in it. Is there a brake saver file or NON Low-NOX file to bump the power a little bit? It needs to stay safe for the turbo and pistons in this engine though. Thanks in advance for any help. By the way I have full access to dealer flash files if anyone ever needs any.

 

Need a little more help. Went to swap number 2 and 5 injectors this morning and found problems with the cam. Cylinder 4 exhaust rocker is pitted and cam lobe is damaged. He’s got to buy a cam anyway. Go back with factory or something else? Thanks in advance.

 

Yes sir. It was running rough a couple days ago. He dropped it off last night so I could swap the injectors. Pulled the valve covers this morning and found the cam. He’s been wanting to turn it up a little since he bought it. I told him there was no point until we swapped the injectors and got it right. What’s the point of turning up a 4.5 cylinder?

 

I’d really like to hear some opinions on a camshaft for this 1LW10696. I need to get one ordered tomorrow. Swapped the injectors yesterday and he says it’s just weak. ET says 374/434 HP and 1450/1649 TQ. Any thoughts? It’s got 90-95psi fuel pressure and it’s making 26-27psi boost using the service brakes to apply load. He’s got a few other trucks with 550hp C-15’s (MXS’s and NXS’s). I guess he’s kinda comparing apples and oranges but I would hate to miss an opportunity to add a little power since we have to change the cam anyway.

 

Thank you. I’ll get it ordered today. I’ll see if we can locate a turbo too. I’ll look through parts ID and check pistons too I guess. Really appreciate the info. Is there any place to get reman rockers other than CAT?

 

I’ll have to go to CAT then. I only have two days to get the cam swapped for him. Thank you for the info. I thought I read on here there were different pistons for the low HP. Glad you could clarify that.
