Hello FTE's;

Stole a 2013 FX4 yesterday, 2 years clean off opiates. 40k miles, cream puff.

5.0L, where do I start?

I have a 3" Spin Tech muffler that will replace the 45 lb muffler; what mods- CAI/tune/other have you experienced power gains with. Bada$$ truck.

Thanks!!!

 

Biggest noticeable gains will be with custom tunes. I have been happy with mine from 5 Star Tuning. I am currently running a 170* thermostat and their 87 octane Perf/Tow tune for it. I opted to go with a "drop in" AFE Dry S synthetic mesh air filter over a complete CAI kit. I prefer a dry filter over the oiled to eliminate the chance of MAF sensor contamination. I also have the JLT CCV oil separator to reduce oil mist contamination of the intake manifold and reduction of fuel octane when it burns. I have the MBRP cat back full 3" SS exhaust.

 

Can't offer any help on performance mods, but congrats on being 2 years clean.
