i get 21mpg on the highway with 411 gears, if you are just getting 16 on the highway that dont seem right but if it was city/highway driving thats about right.

When you change intake or exhaust components you will need a tune. The effects of those components are magnified when running a supercharger. Your cars tune is fine. I'm sure Lethal did a great job on it. Those 22" wheels and stock air box are what's bringing down your numbers on the dyno. Enjoy the power increase, when you're ready for more add some components. Jannetty will retune if you buy from him. If you're concerned about tunes every time you make changes . That's the best deal going.

This the dyno sheet I was given. It looks a little choppy now that I am noticing it

Like Kronix said, different dynos read much differently. As long as you are not going lean, I wouldn't worry about the numbers. I put down 622rwhp on one dyno in 108* heat and then did 658rwhp on a 73* day, on a different dyno with no changes being made to the car.

Do you have a copy of the graph? Was it choppy or smooth? What smoothing factor did they use? You could have had wheel spin on the dyno that gave you artificially low numbers too.

I am not a tune expert but all that choppyness is knock and knock kills power.

Those guys suck at tuning plain and simple. That is the ugliest graph ive seen in a while.

sucks man. get someone down there in texas to do a really good tune for you.

The torque "curve" looks bad. It could be bad gas or an issue somewhere else, but it does not look even remotely close to right.

It should look more like this.... This was done on the same type of dyno you were on with the same smoothing factor. Your graph shows more chop, because the scale is not as compressed, but the torque "curve" is way off.

That's strange OP if he did it.
That's really a messy graph.
And fairly low.
Not typical

Yeah, I heard some good things about them as well, but this visit with them was not good at all. They were changing shops and moving to another, I am guessing they rushed it or something. Im thinking about going to Houston and going to phasetek but that's a 3 1/2 hour drive.

Check engine light came on and the gauge is reading 10.5 on the a/f ratio guage. is it safe for me to drive it to auto zone and get the code read.
