Mike Troyer...parts are on
I recieved the 2# pulley and the 1715 programmer today and the install was easy. I just got back from a test drive drive and all I can say is my truck hauls !!!! I love the fact that you can adjust each shift individually...
anyway
and I sent you the chip for the 98 last Sunday so you might have recieved it already. thanks Clay

Mike can I run my stock plugs for a while before I drop the plugs one heat range? or am I just taking a chance on a melt down.
tr6 or br7 ?

Hi Clay,
Great, glad to hear you got the parts on - thats a very noticeable gain between the 4 PSI pulley & the tuning you've picked up there!
I would not do any drag racing or sustained heavy throttle use with the stock plugs now that you have increased cylinder pressure & load that much - though you *could*, I would not. Remember, each full heat range colder in spark plug will pull another 70-110 degrees C out of the combustion chamber - just what you need to keep detonation at bay with higher cylinder pressures & heavy throttle.
I recommend using the Denso Iridium in a heat range of IT-20. It's a much better plug than the NGK el-cheapo's, or the factory plug, and I would set the gap at .036 - forget the stock 0.42-0.46 factory recommendation, as the stock COP ignition system can't fire that big a gap in high humidity - and sooner or later, you'll run into days with better than 80% humidity, trust me. I lost 7 tenths (added to my ET) on a day with 98% humidity from ignition misfire, just to give you an idea of how bad it can be. Try going from 12.20's on the F1's all the way down to just 12.90's & see how embarrassed you'll be - been there, done that, in front of many people - ouch!
So I suggest (and use) the Denso Iridium IT-20 plugs, gapped @ .036 for best results on the stock ignition - you'll make more power, and make it more reliably - even in high humidity, when any ignition system is straining to cut the ion trail for the spark to follow.
Run the Denso's for not more than 30K miles - I change mine at 5K miles or less usually, but I'm a tuner & constantly reading my plugs, testing, comparing, etc.
I hope that info helps & have fun enjoying your new power this weekend!

Hi Red92,
Actually, I didn't mean to sound like I was "slamming" the NGK's in my last post, and I guess it could have been taken that way - the NGK's really aren't a "bad" plug at all - that's not what I meant, and as I'm sure you've probably been seeing, there are a fair number of Lightning owners who use them - they're actually a fine plug for their very low cost. it's just that there are better performance plugs out there that require less firing voltage, something very important with the COP system & a supercharged engine.
The COP coil packs in many cases deteriorate their output relatively quickly - given that at best, the stock COP setup needs help when significantly increasing cylinder pressure (boost), and what I've personally experienced & observed with it under all kinds of conditions - well, you'll want the most consistent & trouble-free ignition setup possible - and spark plug-wise, that's the Denso.
Just be very precise in gapping your plugs, and the NGK's will do fine for awhile - it's not like you need to yank 'em right back out.
Have fun,
