No power on dyno....limp mode?

[MidnightGT]

Hey guys,

I'm down at Tx2k with my 2015 GT.

As my sig says. Stage 3, e85, twin 67mm tb, 82mm pulley

Ran one time ever down track. 10.40 @ 132

However, when I have put it on two different dynos, reading 440whp???? The car takes FOREVER to wrap through the rpm's, like it's super sluggish. Anyone ran into this?

What kind of dyno was it? Mustang dyno? Dynojet? You get a pic of your graph

Two different dynojets, 2 different locations. It isn't a power problem. This car consistently pulls on 700 whp cars on the highway. It's a dyno problem for some reason. I'll post a pic of my graph in a bit.

Idk? How you do that? Surely the guys dyno'ing the car did, but maybe they didnt. Both locations were LS/chevy builders. So maybe they didn't.

Dyno operators not dyno,when the front wheels are going 0 and the back wheels are going 170 the ecu says WTF!!!.It has to be put in a specific mode to dyno or pull the advance trac fuse.

Fuse number 62 needs to be pulled out. If i remember its a 5 milliamp fuse!

Thanks man. Took it to Boost works down here. Thankfully everyone down here has dyno's rolling. They got it figured out!

Make 630/730 pulling timing up top because we didn't have time to let it cool down. They said it should be a little north of 650 whp, but I'm just glad it got a decent pull.
