Hey guys i need help i finally put the charger on the truck but its got a misfire in cyclinder#1,5,7. my questions is do i need to put colder plugs than the ones that the truck comes with from factory? and if i do what degree are the factory ones? and how much colder do i need to go? please let me know asap thanks guys

 

do you have a Radix supercharger installed?

I'm running NGK TR6 plugs in my truck with my blower.

 

What kind of supercharger do you have? What all did you change when you did the install? What type of tuning are you using?

 

SUPERcharger, TURBOcharger, SAN DIEGOcharger????

i have the ngk tr-6 on my turbo set up. but cly#7 and #2 where misfiring and i blew the motor piston number 7 only put out about 20 pounds of compression so i didnt feel comfortable patching thet motor so i went with a swap and am building the motor that blew. good luck man

 

well guess what cyclinder#7 has no compression the problem is that the guys from nelson tune told me to go ahead and use the tuner but the tuner was programmed to 9 lbs and so the tuner was not pushing enough fuel and the truck was boosting 11lbs but they said since i put bigger injectors it was fine and to go ahead and use it, so you know what happen from there. honestly i messed up i shouldn't have listen to them but i'm a beginner and i guess i'll learn what to do from now on

 

same here i learned from my mistakes also. sts told me to get installed in a shop they knew ( which i went there) sts also sold me a tune and said i would be fine they calibrated everything to sts specs. then 2,000 miles later my motor blew. my rig only has 30,000 miles. i call sts and tell them whats up and all they said was sorry we cant help you . they said my tune was off (no ****) and everything was set to there specs. i dont know **** them. but then i pulled the money back from the credit card haha . go with a good swap man. and just build the one you have right now and set it as a back up
