Well went to the track tonight to see how it ran after the re tune and needless to say I got the ******* red ***. All I can say is be wise when you choose your tuner... Here's before and after time slips. Et got half second slower but picked up 5 mph and 60ft really went to ****!

 

I cant see he pics but it doesnt sound like it lost power it sounds like it didnt hook...

 

It fell on its face at the line. I had it up to almost 10lbs and it stumbled like a **** and afr was pegged on 10.0 the whole way down the track but would imagine it was richer than that. 2nd pass turned the meth off it was on 10.6 all the way down the track.

 

Trap speed indicates power, not et...

 

How bout that 60ft?

 

I can't see it. Post up what it did. Sounds like you need to invest into your own tuning software. Best money spent

 

And this is just a wild guess but it may have loaded up more launching hard at the track and made more boost and the tuner has the area in the tune over your normal boost to dump in alot of fuel for protection..?

 

Went from a 13.0@105 to 13.5@110 with a horrible 60. I could have got out and ran a faster 60.

 

I'm not sure what he's got going on. All I know is its stupid rich with the meth on and 10.6 with it off.

 

So was it bogging off the line or spinning? You lost mph in the 1/8 on first pass with meth and gained 1/8mph on the second with a worse 60' without meth. I think AFR is definitely playing a factor here but it looks as if you are making more power and spinning badly because of it.
