What's up everyone, I have been getting stuttering and hesitation mid throttle to wot.. I scanned the car with the bt cable and no codes or shadow codes.. My spark plugs were changed approximately 6k miles ago and I have 43k on the clock.. I am fbo with jb4 and pump backend flash..

Update: During my logs the car didn't stumble or hesitate at all

Ello! Coilpack sir! one is probably on its way out.

and turn off autoclear and make it happen again(3rd gear WOT low speed<40). do it a couple times and the code should store. Does it run rough after the hesitation? Find the code and swap coilpack and repeat to see if the misfire follows the bad coil.

Anyone?

That boost curve is weak for a FBO car, and the timing takes a hit around 4.2K, builds back nicely at least. Tough to tell what is wrong from the log I looked at, but generally speaking ignition components are the most likely culprits behind these types of problems. I don’t see anything wrong on the fueling side but JB seems to scale trims differently.

That was what I was concerned with too.. Could it be poor fuel? Like maybe try about 2 gallons of e85 as octane booster? I am bringing my car on Friday to get walnut blasted and I am changing all 6 coil packs as preventative maintenance so I will have them give the car a quick check.. I notice the exhaust has sounded slightly different lately and over bumps it almost sounds like something is loose or I am bottoming out which hasn't always happened so maybe its possible I have a small exhaust leak? Also I am FBO with an ER charge pipe but am using the stock DV's with it so I guess it's possible that maybe they aren't holding boost how they should?

I am also working with Ken on a custom backend flash so maybe he can work his magic too

Stock DVs are useless ditch them. But that would only answer the undershoot part of it; your target curve is still very weak.

Wedge will handle it

Yeah I plan on getting Forge in the near future just waiting on some funds to clear up.. I guess all I could do right now is just wait to see what Wedge has cooking for me and then report back just glad to know that the fueling side is looking healthy
