let's see a dyno graph...

 

yeah, you're running REALLY rich. I'm not a pro with kb's but I'd guess you're missing out on a lot of hp

 

What kind of dyno was it? I don't usually car what the numbers are when I put a car on a dyno, I look to tune the car and get as much power increase as possible.

 

it was a dynojet im gonna try to get the dynochart up asap

that a/f is way rich.....that big drop off to the rich side made things real choppy for you up top..

 

Your A/F is about right, you have to run richer with FI.
It should actually be a little richer in your mid range.

And you're complaining about a 120+hp increase over stock?

 

you're right,but 4800-5200 looks fat to me....

 

yeah i guess its not all that bad but i was just curious why kb says like 405 witht the same set up i paid all that money for it i want what they say i am going to get thats why i bought it. i never really thought about it that is a huge gain over stock for just bolting it on!!!
