I've been researching ways to tune my truck after I replace the injectors duramaxtuner.com has a replacement ECM with 5 tunes 1. optimized stock 2.heavy tow over 8,000 3.light tow under 8,000 4.eco street 5.race. for ECM tuned for stock tranny/turbo it's $699 with DSP5 switch. I think this is a good option for me any ideas guys? I was also thinking about an air dog or fass lift pump

 

for that price i would just purchase EFI Live and do it your self. or for less just purchase the tune from a reputable dealer for your own ECM. the DSP switch can be purchased separately for cheap or built for even less.

$700 is a lot to pay for something you dont need (extra ECM)

 

can you tell me how home EFI live works and what I would need I was afraid I would mess something up if I tried it myself. and that price was for my ECM to be sent tuned and returned

in the future if I want to build my tranny how much roughly would it cost

 

i would browse the EFI Live forums and check out the help files to see if this is something you can handle. it is a bit of a learning curve but a fun ride and worth while effort. the amount you learn about your engine from tuning it helps a lot in repairing and keeping it running right later


it cost me about $3200-$3400 a few years ago for a stage 4. this is the 2nd best (efi live being #1) upgrade i have done to my truck. runs so much better the the stock one when under power. it just puts the torque to the ground instead of into slipping clutches

 

thanks so much you've been an awsome help I can't wait to get it running and start upgrading it I recently got a good job so gonna start saving hope to have it going by sep
