I got a 6lb lower and a diablo chip two weeks ago....I was so happy to finally get it cause I was stuck with a 4 and super.....Well that thursday the track was open but I had to go to my Senior prom .....I went this thursday and pulled straight to the christmas tree from the road pulled a 8.84 and a 1.92...I was happy cause I normally do that with the 4 only when the truck was on the cold mark....well I park the truck and get something to eat the run a 8.76 with a 1.96 (Don't know how that happened) Then I ice it down and get ready to run launch and it sputters from 30-40 mph.....don't know why....pulled chip out ran the truck went fine..put chip in wouldn't crank....On the way up there it lost power twice....so no I am pissed and call my man to get out there with his laptop and we were going to fix my chip...but he couldn't...so what is going on? I pull my computer re clean all the terminals and truck runs like a champ now...but I don't understand it cause I had the chip in for a week b/f any problems....But I am going to get put it on a dyno this week what type of a/f # should I look for?

 

Hey CH,

Make sure the chip isn't loosening itself from the 'extreme' G forces and coming out a little. Everything has to be secure. Some guys have even created little devices to hold it in place. Or you can just use tape
