How Much Boost before Boom
Junior Member here, probably asking a question that has been asked many times.
I am the proud owner of a new 03 Lightning! Here are the mods I am planning, all parts have been ordered and are on their way.
KB twin screw and chip
Johnny cold air induction
Bassani cat back (spelling ?)
Denso 22's
Valve Body for Trans
Traction Bars
Deep trans pan
Rear lowering shackles
Drive shaft loop
Thinking about the 90 mm throttle body?
I have been told the following:
From KB, stay around 14 lbs of boost unless going to higher octane.
Lightning tuners tell me stay under 16 lbs unless you are planning a lower end up grade.
I need to hear from you, the experienced ones - How far can I push the boost with the understanding that at this point I am not planning a lower end upgrade, but I am willing to move to 100 octane? My L will be used for weekends and the occassional shot at the track.
THANKS
I am not going to be able to get back to my email until tomorrow so any suggestions would be greatly appreciated!

Dan,
Congrats on the new truck, you will love. I just as excited about mine as the day I got it (10/17/01).
Sorry I'm not an "experienced one" since I'm pretty much stock.
Hopefully someone else here can help you out.
But I can tell you that the Gregg Evan's Factory Tech Valve Body is frigg'n awesome
I love it!
What color is you 03? I'm in Bonita, I just met a nice guy with a 2000 Silver L the other night in San Carlos, funny his name is Dan also.
See you around...

Actually, I was being facetious, as I am sure you are aware. But I tried to send you a serious reply via e-mail and was informed that you had disabled that feature. I don't know why you would do that if you want answers to your questions, at least from those of us who are reluctant to start pi$$ing contests on the board.
James, thanks for the message.
She's a black beauty and I can't wait to add my mods and get her on the track. The guys on this sight are awesome and have helped me through the decisions of what to buy and not to buy. I am just stuck on how far I can push it?
Hey do you belong to the SVTOA club? and have you been to the third Tuesday of every month events at Galloways?
I couldn't hook up with anyone this week, but I am hoping to meet local owners next month?
Let me know what you know.
Thanks, Dan
I heard Greg's valve body gave you an excellent hard shift and I am very glad to hear you think it is worth the money.

The answer to your question is not how much boost you can run but rather how agressive of a tune you run and actually how you run your truck. Your truck probably would do well with around 18#'s of boost with a mild tune and no 140mph wide open blasts. JL I think is running a KB on his Harley with 23#'s of boost on the stock bottom end with no trouble at all.
Give him some good info all,
I've been talking to Dan the Ligthning Man
quite a while now and I asked him to come
hear to F-150 and learn from the Pro's.
Dan I'm answering your other e mail privately
Glad you showed up.
WELCOME
AND CONGRATS

what can I say, just like you I have it in my blood and what the hell life is too short, warranties are too limited and show me those 11's on the quarter.
I can't wait!
