Ya, I just did a mail order tune from Nelson with mine. Emailed in, told him lsx 427, twins, good to 20 psi... He sent it... That was 2 years ago and I still haven't touched it.. No joke

The best advice I have ever heard:... Only take B( . Y . )ST advice from someone that is CURRENTLY running a turbo setup close to, or bigger than what you want......
Also, if you get pro you can get a mail order tune from Nelson and do scans and he will tweek it forever, you can see what he is changing in the tune to get results. Just my $0.02

I also have had a nelson tune since i started do'n mods on my truck. I've been extremly happy with them up till now. I just did a T-56 magnum swap (had a NV3500 5 speed) on my ride and had nelson sent me a tune. Like i said up till now they've been great, but since i put that tune in the speedo wont go above 25mph (was going 75 according to the garmen) and my service brake system light on the dash came on along with the ABS and parking brake light... IDK what they sent me (probably a ford tune xD) but it does not agree with my setup...
Im probably gonna have to drive 2 hrs to the closest dyno and get it dyno tuned... Fail

My ABS and parking brake light came on due to a bad wheel bearing. Aren't those controlled by the bcm anyways? Have you checked the speed sensor on the trans to see if it may be the problem with your speedometer?
Tire siZe in tune can cause abs to act up
Slowest in Oklahoma...
All of those things could easily be unrelated to your tune and could completely to do with wiring issues when you did the swap.Originally Posted by Silver05RST
