Get rid of that programmer and get a nelson tune and ull get more power.

i had the truck dyno with and with out the programmer and with out it it was 229 at the wheels and with it i was at 270

yea you will see an increase, but as stated programmers mess with very little in the motor. imagine what a true tune will do for you. i bet it gets right around 300 with the change over to tune.

[silverado120]

well i guess i should sell it the only problem is i cant take the tune off of it right now cause i broke the programer so i wasnt sure if i had a custom tune would i have to buy a new programer and uninstall the tune thats on it right now

Thats not tru. Nelson will send you a new pcm and you just send them your old one.

[silverado120]

about how long would you say it takes before i would get it back

[WARLOCK]

I dont think you understand. THey send you a new one programmed and after you put theres in you have 30 days to send them your old one. Thus there is NO down time.

[silverado120]

o ok i didnt understand you at first but now i got it do they need a list of your mod or anything like that

[WARLOCK]

Yeah its all on the order form.
