Tuning
I am slowly learning and understanding how to tune,I also haven't seen much on here about tuning.
Anyways I stumbled upon this and thought it has some pretty useful info so I thought I would share with the rest of you..

hello eddieavila,
Nobody else seems to be answering to you so i'll take a stab at it.
First of all, i am not a tuner, i recently bought an HPTuners and am learning with it now.
A few questions about the attached chart:
1) what are those dips in torque at high RPM? Slipping on the dyno? unlikely. Misfires...? if so, it's a little scary that someone would use this as their bragging rights if it has problems.
2) The darker red line is supposed to be whp, however why doesn't it have the dips that the torque does? is it because it is hand edited on top of the picture? kinda scary?
3) Assuming the bottom graph is AFR, I am a little too unexperienced to comment on this AFR, but it looks a bit lean to me. The real concern is that it gets LEANER at higher RPM, if anything it should be getting richer or stay the same.
4) to make that kind of HP, that is not a stock turbo, so if you have a stock turbo, you will not be making that power. This is stating the obvious, i know, but i do not know your background and how familiar you are with what these cars can do.
5) without knowing what was done to that car, or what the tune does (boost, spark, AFR, etc) there is no way of saying if this is a good tune or not.
