That dyno chart is hard to read.
So the fastman throttle body gained a bunch of low-end torque but over 3500rpm it was basically a wash, and it lost peak hp but gained a few above about 3800 and a lot under 3400?
What other mods does that motor have? Was it a chassis dyno doing a guestimate of flywheel, or an engine dyno?
Not bad numbers, but to me it honestly looks like the torque converter lockup happened a little lower on run 2 causing the much greater low-rpm curve, and from there it seems like pretty much a wash between the TB and a CAI.
Glad I only paid $100 for my FIPK.

I was surprised to see such a gain in the lower rpm range. Like you said, I assume there was a lockup error of some kind as well on the first run. A larger Tb will always give you higher rpm gains, not lower. However, with the mods this truck already has (Owner is superdak05 in the gen3 forums) significant HP gains in the lower rpm range could be very possible:
206 Cams, PCM piggyback Jet stage2, catback exhaust, punched out cat, "iat adjuster", 93 octane, K&N intake.
I took this from here:
http://www.dodgeforum.com/m_633000/tm.htm (12/2/2006)
He most likely has done other mods since this post. For further infomation on his mods, contact him:

i know how the stock box has a down tube...BUT if you see most of the aftermarket CAI kits don't have shrouding..this if you look back is what i was talking about not attacking your truck...

Chris i would swear you have stock in CAI kits......keep your panties on...hehe.
I think the bottom line is, you will gain a little HP if the diameter of the CAI tube is larger
than a stock one AND only at wide open throttle....Because the air is being sucked in faster
than it can heat up in the very hot tube in the very hot engine compartment....
AGREED ???
Furthermore Chris, don't think that heat shield is foolin anyone.....When your hood is closed
the entire engine compartment heats up...That big beautifully air filter you have is sucking air from
where ever is close ....which happens to be your engine compartment...
In your favour,that gorgeous 4" stainless steel tube will help get the air in quicker...
Remember....Just my opinion

i second that! i like them like others have said, they sound cool, gains...not really, i think its a mute point its like all mods its what the owner wants, doesn't mater what anybody else thinks as long as the owner is proud of it..

I've made all my CAI. and I'm backing virused up on this one.
his heat shield will bock the hot air the fan from the motor is spinning around. and if you look at your truck. you will see the holes in the fender. and it will suck air in from there. I'm not saying it's pulling in 100% cold air. but its pulling in a good amount.
alot of people will buy an intake with out the heatshield. and it will just pull in hot air from the engine bay. the first intake I built for the 99 did that. then later I put on a diamond plate heatshield. and now it sucks it in from the fender.
and the intake I built for the 88 is 100% cold air. I attatched a piece of pipe to the TB and the added a cone fiter on top of it so the filter sticks out of the hood. so it gets 100% true cold air. and when it's raining, I put a cover on the front of the scoop to stop the rain.
so lets end this stupid debate

Are you kidding me jonnymagnum.....Have u seen virused setup...I know there are holes in the
fender....But no matter how much u WILL it to pull air from there,without a sealed tube GOING there,its
not, its going to pull from around the filter....Which is still in the hot engine bay. Sure there is outside air mixing with the hot engine air but with the hood down its not going to dissipate as much as running a tube right to the fender hole.
In order for JUST air to increase HP it needs to be as cold and dense as possible, so taking it from the engine bay (whether there is a piece of metal blocking one side or not) is not going to be as efficient as taking it from OUTSIDE the engine compartment.
Love your setup on your 1988 dodge by the way....VERY COOL....lol...no pun intended.
I agree the horse is dead !!!
