So I just bought a 01 4x4 lariat with 209k miles. The truck doesnt skip a beat and feels more like 50k miles. Will I be ok putting a custom tune on it? I dont need anything real aggressive just wont something to make it a good daily driver on a 87 octane tune. Coming from a tunned 06 F150 I dont think its possible for me to drive a stock fiddy ever again!

I would do a compression check on the engine and make sure you are within specs on all cylinders... If all is good and the rest of the vehicle is mechanically sound, you should have no problem running tunes on it

Personally as long as the truck is in sound mechanical shape and routine maintenance has been performed then a tuner won't be an issue.
To do a compression test at home you need to go out and buy a tester gauge. Remove spark(s) plug and put adapter in the hole and crank the motor. Another GOOD investment is a Haines or Chilton repair/service book what can be purchased/ordered at an auto parts store or online. Peace! ![]()

Might be cheaper to take it to a dealer, or someone who has an IDS to do a Relative Compression Test. They can preform this test without even opening the hood, and it is very accurate.
![]() I am with 88 on this, if the vehicle has been well maintained I would not be the least bit worried about adding custom tunes. Just a thought. |

I wouldn't worry about it.
If you want the improved custom tune response and shifts then get them.
