Hey guys, can anyone help me with a tune for my buddies 02 silverado 5.3/4l60e tune. We just put a 224/224 cam in the truck and he has the stock stall in the truck. He just drives it through town,...

I made a bunch of other changes also. I cant remember exactly what they were, but somewhere in this forum is the list.

Can someone look at my tune and help me make the changes to turn my sd mode tune back into a maf tune? Its been so long since I did it that I forgot all the adjustments that need to be made. ...

What about the final drive ratio fields? What is the difference between the 2? the truck has a 3.73 rear end in it. the ratio field has 3.73. the trans field has 4.10. What is the difference?

What about the rev - trans, and rev fields. right now they both have 40 in them. Do those need to be changed?

How can I fix the speedo for taller tires? the tire height and rear ratio boxes don't show up in the tune. 3.73 gears with 31.6 tall tires.

I tried to fix the speedo on my buddies 05 silverado 3500, but the tire size and gear ratio boxes don't pop up. How do we fix his speedo for taller tires????

He says when those codes are on, the car runs like absolute crap. Any ideas?

Well I tried to load an m6 tune file, but it would not let me get to the flash menu. Any ideas why?

Im doing an a4-m6 swap, and need a m6 tune to load on the car. When I try to load an m6 tune it won't let me flash it to the pcm. What do i need to do?

That I can do. Any clue about the timing falling to 0?

Also, why would his car throw the code for knock sensors if they have been turned off? He is getting the p0332 code. I believe you turned them off Russ.

Ok I'll have to do that when I get home. Any clue why the timing is going down to 0?

Sorry,I can't find the formula. Where would it be? what graph are you talking about that is dropping to 0? Any clues why it is?

Anyone have any ideas??

Went out tuning my buddies firehawk tonight and we ran into a popping/backfiring issue. Around 3k, 5k, and 6k it will pop and lose power for a split second. Im leaning towards a timing issue, but...

Thanks for the info. Can't wait to get started!
