i have a predator tuner that ive had for awhile,im running a stacker tune{extreme rkl stacker}i just bought a used quad race and ran it on low then tried it on full and got the 0088 code{rail presure to high}and truck sputtered and bucked then ran ok,cleared the code and it hast came back,does the quad make more pressure than the puck?i had a puck with no issues,other than that the quad is awsome. thanx

 

The Quad does more than just pressure. You should send it in and have them reprogram it so it's just a pressure box. Then you should be fine.
