Just a little IE hardware upgrades for your viewing pleasures on my 19 S4. Been working with IE over the last couple of months on tune revisions. I ordered the IE Turbo inlet before I realized that it only works with their CAI. So went ahead and pulled the trigger on the IE CF CAI so I could use the IE inlet. Luckily I knew the challenges in trying to remove the inlets and had the experience and tools to handle the job. All in all it took me just at an hour from start to finish to take out the old 034 CF CAI and ECS Tuning turbo inlet.

Next mod will be the HPFP and then update to the Stage 1+ E85 tune and see how the S4 responds. As of now the S4 has already responded very well, granted the weather is 38° and the D/A is -350'. Even so the car just pulled it's best 0 to 60 to date (3.4 seconds) and it's best 1/4 mile on Dragy at 11.55 @ 118.6mph. The D/A was only 350' better than my previous attempt, the data is showing the car is making more power down low so the claims of increased air flow and less restrictions can be seen.

One of the issues I am running into now is with the really cold and dense air with me being on E85 I am becoming fuel limited on my WOT pulls, so much so that the ECM is having to pull boost back and causing me to lose power. My prior best runs were 11.61 @ 118.5mph, with us finally being in boost weather I have been struggling to get back into the 11.6xx range and over the 117mph range. I am hoping with the IE HPFP upgrade I can get some of the cold weather boost back that I am losing due to being fuel limited on right now back and get lower in the 11's and then call it done.

Of course here are some PFA...
