ive got a superchips flashpaq on my truck, and am wanting to put another chip on as well..im looking at a dr. performance predator chip that my buddy has...will that stack ok with my current programmer? i thought i would ask...he is leaving for military and is willing to sell it to me for 75 bucks...not a bad deal considering it hasnt even been used yet!!!

 

you need to check and see if both programers add timing.. that is a no no
