Hey there guys:
I am driving a 2001 Dak sport with a v8 TB, home brew intake, autolite 3923s and an IAT adjuster.
I have real good acceleration off the line, but when I floor it past 60 mph, the acceleration drops noticably. What would be a good mod that would help me gain some acceleration in the top end? Thanks guys...

ahhhhhhhh yes let's see what is in the old bag of tricks ( actually this is a bernd trick )....
ok go out and buy a volt meter if you do not already have one, then go remove your TPS sensor from your throttle body, take a 1/4 in drill bit and drill out the brass inserts in the TPS sensor..note ( you will need to lock the sensor down in a vise to do this ).... once you have enlarged the holes reinstall the TPS sensor but leave it slightly loose, now take your volt meter and install the red probe into the weather connector on the tps sensor in the center hole ( orange wire with blue tracer ) take black probe and touch it to the negative lead on your battery, then go into your truck and turn the ignition key to the on position but do not start the truck ( make sure all your dash lights come on , u know the usual when you turn on your truck like your going to start it ).... then go out and check the voltage on the volt meter to see where it is at, you want the voltage to be at .7 volts, you can adjust the voltage by turning the sensor forward or backwards, once it hits .7 volts, lock down the screws the rest of the way but leave the volt meter connected so as your tightening you can watch to see if the voltage moves, if it does just readjust and continue tightening... with this i found that the truck no longer bogs quite as much when you go straight to full throttle and the overall throttle response is much improved... also if you want more top end i would suggest either a flowmaster 50 series muffler or a 40 series delta flow muffler for more top end pull....

P.S. any ?'s go to bernd's site the address is wwww.speedtweaks.net in the tips and tricks section you'll find the how to on the TPS sensor just in case i wasn't clear enough.

I just bought a 50 series delta flow and I'm really happy with it. The 40 does sound a little deeper but let the 50 series break in a little and it deepens in time. The 50 series delta flow is the way to go. Greg

the 40 series delta flow is much deeper then the regular 40 series but if i recall correctly i don't think flowmaster even makes the regular 40 series anymore.... anyways if you go with a 40 seires delta flow keep the cat and the pre-cats on or else it will sound like a honda.... mine sounds really mean and is never raspy but i will say that the 40 series is a HUGH improvement in low end torque and it makes awesome torque thru out the powerband, my truck no pulls hard all the way to redline and never feels likes it's running outta breath plus i did also notice my temp gauge drop a few degrees since i added the exhaust....
