tune yesterday....breaking up after 4,500rpm
whats up guys,
i just wanted your opinions on this,and let me know what you think
yesterday i went to go get my turbo LS tuned with hondata. we didnt even get a good pull in. the car kept breaking up around 4,5-5,000 rpm. so my tuner thought it was the plugs b/c my air fuel was good (i think it was around 11.7) and the ignition was very conservative. so we got new plugs (ngk brk7's) and did a pull. still same result but we did get like 1,000 rpm more then before. now hes saying something in my ignition (distributor,plug wires,etc.) is going weak,that i need to replace and come back. does this sound right? like i said air/fuel was good,and ignition was conservative,so what else would make the car start to break up?

sounds like distributor/ignition problem possibly. how much boost, how much hp, and is there an msd on the car?

This is WAY out there, but is everything setup correctly with your ECU & wideband/narrowband?
I had a problem at the track this past Sunday w/ my car throwing itself into limp mode. Turns out one of my friends had knocked the narrowband wire from my PLX off and put the wideband wire on instead.

plugs are gapped to 28. the ignition system is stock,no msd. im not going to fool with any aftermarket ignition system b/c the stock ignition system (in good working order) is good for 400+whp.

sounds like a bad dizzy to me...i tuned a car that did the same thing...the bearings in the dizzy were shot and it wasnt working like it should...new dizzy problem solved. (haha we replaced EVERYTHING in the ignition before trying the dizzy haha!)
