Anyone know of a programmer I can use on my 1995 f150 5.0/302 4x4? I saw jet makes a plug and play one (summitracing.com) but what are the power gains from this? I would like to know if anyone else makes a decent tuner. Let me know your thoughts gents!

 

Nothing... If your truck is stock or wen lightly modified it needs nothing other than timing bump.. Hell I got a built 5.0 and still on factory tune and exu

 

chips wont work very good on these trucks unless you get a throttle body spacer to go with them.

 

I thought throttle body spacers were a Waiste of time? And what's with the timing numb stuff I hear ppl talking about this all the time

 

Please don't ever speak again if you think a throttle body spacer does any good..


To OP: A timing bump is where ya adjust the base timing from factory 10* to 12-14 and at same time do the 6 litre tuneup.. Consists of putting a high spark coil on, 8.8 or 9 mm plug wires, new cap & rotor, and new plugs gapped around .055.

^ gives better spark distribution which is minor performance and efficiency bump:.

 

Well that's great because I already have all msd ignition! Haha just need to gap spark plugs and adjust for bump. How exactly do I adjust timing and at how many degrees? Also does this make your truck less reliable? If so then I'm out on this one

 

WHAT!!!! TB spacers are great, I had one on my truck and I couldn't be happier, it has been performing as a paperweight on my desk since I got my truck, and I couldn't be happier with the performance it has provided. just think of al of the times it has saved me from chasing wind blown papers, holding open a manual for me,

 

^ thank god you were being sarcastic.. I thought you were I just couldn't tell

 

It dosen't make the truck less reliable, but you might want to inspect your plugs a bit before the service interval to be sure they are not burning off the electrode.

To do the bump you need a timing light, don't do it by ear like some people do. You need to pull the SPOUT plug on the drivers side fender near the module and loosen off the nut on the distributor. Clean off the timing marks on the harmonic balancer and use some chalk if you have it to make the marks more visible. Start the truck and let it warm up then shine the light on the timing marks to see the timing, stock is 10deg BTDC. Turn the distributor counter clockwise to adjust the timing up and set it to about 12-14deg which are the safe numbers. Too high will make the engine ping with 87 Octane.

When you're happy turn off the truck, tighten down the nut and put the SPOUT back in and go for a test drive.

 

This also depends on overall condition of your engine. I got mine up to 16 without any firing issues. Other than that little difference with mine you're spot on.

Regular maintenance, seafoam treatment, and a better than stock drop in air filter also helped mine (I use k&n because my brother already has the "recharge" stuff for k&n air filters)
