well i have installed the chip and underdrive pulleys. do not buy this chip, i see no difference except a little better throttle responce, the pulleys gave me about 10 extra whp. now i'm installing pace setter headers. if anybody has them tell me if they are a good up grade.

 

ive told people for years that that venom 400 is crap along with many others. they are junk.

as far as the pullies go. you may have gotten 3-4 hp at the very most.

 

I always wondered about those things. I remember them claiming 25% more horsepower at wide open throttle...sure

 

Well, the 3.4L has bigger weaknesses than the computer programming.

NO piggyback helps when it comes to having crummy heads and ports...
