If tuning is not in your plans then I would suggest the Pedal Commander.....easy plug and play .....no more lag

I also removed the factory black vinyl door pillar wraps but went back instead using a 3M gloss vinyl wrap. Looks really good in my opinion as it blends nicer with the glass and rear window tint.
My Eco is running so awesome now after installing the SFT ECU and TCM Tunes from Jimmy. MPG's are definitely improved but it's the performance curve that is so mind blowing! Completely different truck now and I am looking for any excuse to drive now...it's that much fun!
Cheers!
