Have there been failures with DYNO tunes? Sorry if I missed that in the thread. If not, then maybe that's something all the Coyote owners need to consider.

I wouldn't trust 90% of the dyno shops to tune a coyote engine. There are a lot of parameters to mess with and only a handful of tuners actually do a good job on the 2011+ GTs

I suppose a good question would be whether Brenspeed has had any #8s fail on any of their dyno tunes vs. their mail tunes.

kzonts

Good point. I meant a reputable tuner, not ACME Dyno. :-)

Mishri

then you run into the issue of #s, thousands of people have e-mail tunes but probably only a few hundred have dyno tunes. and if it's a 1 in 1,000 odds (or even higher odds) that you have an issue there aren't enough people with dyno tunes out there to see.. I think all of the cases ive heard of had email tunes, I'd be interested if anyone had a dyno tune and the #8 issue though.

Well I actually just spent about 4 hours reading over all the other forums and there is a 17 page thread over on SVT Performance that is somewhat good but is also full of plenty of trash, if you want to burn about two hours of your life it's an "ok" read. There are 4 guys in that thread that have had their #8 go and they were all from different tuners. On was a Lund tune but supposedly they guy got some bad gas, one was from Brenspeed, one was from some shop I've never even heard of, and one would't say.

I think anyone that gets a tune should data log the car probably and not just assume that the tune is good to go, there was another guy on there who got a Bama tune that ran 14:1 AFR, if he wouldn't have found that out it wouldn't have ended well but he caught it and they fixed it for him.

So on Monday or Tuesday I'm going to be loading my own 93 Lund tune and I have never "data logged" a car, just how do you go about doing this? I'm assuming there is a device I'm going to have to purchase.

I was also surprised to see how much traffic the other sites have on the 5.0 engine, this one seems kinda dead most of the time but by far and away the most grown up with the least amount of trash.

2008gt/csbuckeye,

You have a Boss right? They have the nice forged pistons that I bet are not near as likely to give you issues with the ring lands cracking.

Also, your SCT tuner will provide you all you need to data log. You just install the software on a laptop, connect the laptop to the sct, and the SCT to you car.

Thats kinda what I thought but I wasn't sure, I'm confident in the tunes and stuff but it's probably still a good thing to do. Thanks.

You got me interested in data logging, so I went and found what I could.
