Rep Power: 280

here is my dyno graph (slightly tuned0
I have about 170 tq at 3000 rpm
When I accelerate hard off the line, I get wheel spin when engine comes to 3000 rpm, it gets tiresome in during wet weather.
I want to know if there is something I can do to move TQ band to later rpms ???

Larger A/R or Larger turbo. Cam gear adjustment can work too.

You are saying a different turbo.
How would cam gear help?

Looks like your ignition timing is way off from MBT. If you move it closer, not only will it improve your torque curve, it should improve your hp numbers alot too. You need tuning, man.

what is MBT?

just a guess but are you running LEAN from 2500 rpm to 3500 rpm? If so fatten it up a bit. It looks like max TQ at 2800 rpm could be because your leaning out. Do you have AFR plot also? My max TQ is at about 4800 rpm but you are running a T25 this could be part of the low rpm max torq. I would suggest more tunning before swapping to a bigger turbo

Yes get a good tune first....to answer you other question, the cam gear will push the graph forward.

MBT=Maximum Brake Torque
Basically it's the point of ignition timing that allows for max torque but not necesarily max horsepower. It has to do with how you tune an engine to make the most horsepower. Alot of people don't understand that air/fuel is only part of the tuning process. If all you had to do to make power was get decent a/f mixtures, everyone would be able to tune. That's the importance of the dyno, not to just "get a good number." You have to find the point in your ignition timing where everything is optimized.

Thanks for the input pple!
I only wish it was warm outside, so I can work on my car...
