Preaux Tuning

We are pleased to announce we will be offering a plug-n-play fuel rail and line kit for those 21+ F150 5.0L forced induction guys who want to eliminate the limiting factory fuel rail setup. The factory rail setup places the fuel rail pressure at the tail end of the bank 2 port side rail, which is furthest from the crossover to port transition, which on high power ethanol setups can cause that sensor to see a reduction in pressure due to the location and limitations of fuel getting to the sensor. This can skew the fuel demand sent to the lift pump causing the pump to work overtime to satisfy a potentially false fuel demand. Not only does this setup look killer but its intent was pure performance based to allow proper tuning to extract as much power as possible from both the direct injection and port injection systems. The kit includes all of the fittings needed to connect to existing lines, rails, spacers, and line support brackets. Check out preauxtuning.com to get yours today!

And the testing continues! ESS, 100mm pulley, pump e85, modified GT Manifold. Let's see if we can max out this JMS voltage booster... I think so.

I am trying to use this downtime to further progress my knowledge and perfect setups that I've offered tuning for. The best way to do that, in my opinion, is to own and drive each of these setups everyday. So to have the time to tear down each setup and configure the next, takes time and effort. It is has been refreshing to be able to focus on what is most important to me and then still have some time to make what I offer even better. Thank you everyone for your patience, I will be opening up tuning again in the next week or two.

After giving it some careful thought, I have decided to put new tunes and tuning bundles on hold for a couple of weeks. I will be disabling the purchase options from the website until further notice. I am a one man show over here with a family and a full-time job along with Preaux Tuning. I absolutely love tuning and giving customers my all, but more importantly I love my family and giving them my all. So, for the remainder of the month, I am not accepting any new tunes or customers. I will work through my backlog and spend as much time with my family as possible. Those who have pending tunes, I will get to it as soon as I can. Thank you for your patience and understanding everyone!

Morning everyone! My apologies on delayed log and data review, I have been extremely busy with family matters and feeling a bit under the weather to boot. I will be catching up over the weekend. Thank you for your patience and understanding.
