Ignition Qs, want to do it right the first time

I would love to give the entire story on my truck but it would be just to much typing. I did talk to Harry Anderson last night and explained the minor problems I'm having.

My truck came from Redshift Motorsports on Sunday. Chris tuned it, was able to get 21psi on a TE45A turbo with the alky/water injection. Timing was set around 19-20 deg. advanced. In the future I need a better intercooler. It is not stock, but I guess a upgraded water/air. Anyways, it is not getting any knock and very safe at 10.5-10.6 air/fuel ratio.

So, I had to turn the boost back down to 15-16psi and take away some timing just to be safe because of a current problem. It seems most likly a spark problem. I'm just going to go ahead and replace each item until I find the problem. So...

Starting with plugs, I hear I should run NGK 6s. Can anyone give me a part number or best place I could get these plugs. I have brodix heads and will run 20-22psi of boost once the problem is gone.

Spark Plug Wires, I seen the custom ones from RPM. Anyone else know of good ones?

What cap and rotor? RPM sells a performance set.

If I have to, distributor? MSD stuff? Someone make some post and inform me. Anyone who can shed light on what exactly to do, with part numbers would be great. I currently have a F.A.S.T computer system in which was used to tune it. Thanks guys!

I guess it would help if I posted what exactly my problem was. Under boost it misfires. During regular driving, it drives fine. Its almost like the spark is blown out or something under boost. The thread only got one veiw...I was hoping for quick answers so I could order my parts over the weekend...

I'm not sure what plug the Brodies take.... I've got a set of Brodie 10's waiting for a motor build but haven't even researched the plugs yet. Get whatever the equivalent of an NGK UR6ix is, in an NGK iridium for the Brodies.... gap them at .028 to start with.

I put Magnecors on my Sy.... very nice but expensive. Take your current plug wires and do a resistance check through each one making sure one isn't way different from the others. Check continuity on coil wire, then check your coil by doing this...

I would think this would be the obvious place to start.... what is the ECM voltage reading on the datalogging software you are using?

magnacores in my opinion are the best wires out there,better than the taylors i think.

Well I'm going to bed for the night...hope to see some more replys and maybe some part numbers for the specific plugs I need. Once I have some more of the info for you WyoSyclone I'll post it up. Hey cloneman, how do you like your Mccoy IC?

i had some spark blowing out issues, so i closed the gaps to like 20 and that fixed it

Maybe I will try to change the gap tomor. Good night fellas, looking forward to getting this running good again :rant:

Im also interested in this as i have some possible misfire under boost. Drives fine normally til i hammer it. I run the ngktr6 gapped @ .026. I have msd wires and coil and same issue

try closing the gaps even more

That is the first thing I will try before doing anything. Rather not buy extra parts if I don't have to.

Anyone use those custom spark plug wires from RPM? They say they have an extra 600+ temp. resistance. My headers are way to close to those wires I bet... :rant:

i have had the same set of wires for 5 years and i have headers
