I just got a ZZperformance tune for 42lb injectors. for some reason when your driving doing around 10psi boost the fuel will cut for a second after like 3500 or 4000rpm after that it randomly does it. it doesnt do it often just sometime but when it does its like hitting redline in the middle of a gear. my friend said its the spark plugs but i thought i should consult this forum before doing anything. if anyone has any info on why it is doing this pleasse post this thread....THNX..

 

Check your codes If your misfiring you should have a p300 I think.

 

Could be the tune, could be the plugs, could be a bunch of ****.

Start with the plugs IMO.

 

Did you ask ZZPerformance?

I've delt with them in the past and I've had nothing but GOOD experienses with them.

 

my friend said that all i need to d is regap the spark plugs. and am in the heat range for one step colder ngk iridium spark plugs?
