OK guys I need a answer to a question. I have a hsw plate jetted for 150. With a zex tps box. This setup is on an 04 Avalanche. My question is that if I spray below 20 MPH the truck falls on its face. Any help would be appreciated.

 

What is the rpm when you do this?

Rookie mistake I figured it out......... traction control. But omg this thing woke up. Can anybody give me a general idea on how long before the tranny says no more, I have all of the goodies setting to the side just can't really afford to do it right now.
