Well, I know about next to nothing with trucks (except to change the oil...that's about it), but I want to learn. First thing that I've heard about it changing the chip in my truck.

I have an 1990 F-150 XLT Lariat, 5.0L Automatic w/ O/D, 127,000 and 2wd. I'd like to beef it up quite a bit and get more Horsepower out of it, but also not kill my mileage (Currently I replaced the exhaust system on it and I get about 14 city and 20 highway)

What can I do with the chip? Also, can anyone suggest literature to read up about?

Thanks!

 

Merlin: Go to the chip sites and read up on the different chips. A couple of the sites are: http://www.superchips.com
http://www.diablosport.com
Both companies guarantee that your mileage will not decrease. Both claim a 10% horsepower gain, which is 20hp, and a 30 ft/lb torque gain.

What else can I do to get more power out of my truck with out the sacrifice of mileage? I don't want the 110 MPH speed (its dangerous in that truck at around 100 because the top of the bed develops a low pressure revolving....hence lift and almost no traction)

But I'm looking for 0-60 times to drop. any ideas? Already went to exhaust route....but nothing too expensive. What can I do on my own? I don't want to pay a mechanic because I want to learn.

 

Merlin: Costwise, a chip is the cheapest horsepower you can buy. If you figure dollars per horsepower, nothing even comes close. Example: Exhaust system cost about $200.00, adds about 2-4 horsepower. Headers cost $400-600, add about 3-5 horsepower.
A gasoline engine is nothing more than an air pump, the more air that you can pump, the more horsepower that it will produce. Look for ways to improve the air into the engine and out of the engine.

Do you think I should go the Diablo, or the Super chip?

 

On your year model truck, Superchip will most likely be the only company, of the two, to have a program written. Diablo has a few of the older programs, not many.

True, so don't you think a K&N FIPK would help him out? Plus, since his engine doesn't have coil packs, he can get more of a performance boost by advancing the timing to 13 deg and adjusting TPS voltage to .99 volts. This will yield almost twice as much hp gain for zero money spent! Plus, he could probably get away with running mid octane gas (89) whereas the Superchip requires 92 octane or better. If he wants the transmission improvements that the Superchip would provide, he could get a Transgo Shift kit which will yield substantially better results than the chip (for about 1/2 the price if he does it himself or about the same price if he has a shop do it.)

 

I have a '92 Nite i've been looking over for horsepower options. It to has the 5.0L Auto/Overdrive. Would i experience the same gains with the timeing and TPS voltage adjustments?

Yes! Here's the procedure:

Here is from a stang to set the voltage on the TPS:

Principle: You can adjust the TPs to a higher setting than stock, the 0.98 volts to make the computer advance the timing and adjust the fuel mixture sooner for more power. This is the same idea that youv'e seen the TPS plug in devices that sell for $100.
Procedure: (To find the TPS, look at the shaft in the TB. It is the part on top of the shaft with 3 wires coming from it.)
You will need to disconnect the TPS wiring harness. Then remove the 2 screws that secure it to the Throttlebody. You will need to use a drill or dremel tool to elongate the holes in the TPS. Make them oval in shape. I did this with a drill bit and it worked very well. Try to follow the natural arc of a circle.

Reinstall the TPS but do not fully tighten down the screws. Make sure that you can twist the TPS on the TB.

Pierce the green wire coming from the TPS with a safety pin and hook the Positive, red, lead from the meter to it. Ground the black negative from the meter to the TB housing. Turn the ignition switch to the on position. Turn the meter on to DC Volts. Now rotate the TPS until the meter reads 0.98Volts. Tighten the screws and remove the safety pin. Tape the wire where the pin was inserted.

Hope this helps! Feel free to e-mail me if you have more questions. I might not be able to answer it, but I have a buddy that has a Stang and has done this.
