well just installed stage 2 w/o toys and the first day wo the recommended sparks i was boosting normal: spiking around 18-19 and falling down to 15 at redline. so the second day installed NGK sparks and was only boosting till 15 and holding there till redline. Is there something wrong with sparks or does the comp still have to learn. or worst of all is this how stage 2 is supposed to be. WGA at 4mm. need some advice for others who have had this prob

 

did you rest the computer?.......also what gap did you set them at?.......from what ive read......boosting to 18 then falling to 15 is about right

 

Have you tried readjusting the wastegate actuator?
What are your plugs gapped at?

 

I know you guys will disagree with me... but you really don't need to regap the plugs (assuming you are running iridiums, can't speak for the nickel V-grooves)...

 

was there a change in the weather from one day to the next?
