shifting issues? long gear climb before 100mph

[Big Mike 74]

Car is a 2013 pp...When I floor the car wide open from 60 with out being in paddle shift mode before it shifts at around 100mph I'm not sure what gear that is right before redline its almost like the car idle goes up and down quick, I'm wondering if its a slipping issue and praying its not but from a dig if I launch the car and go balls to the walls it shifts perfect no issues, I have no codes, the car has Livernois 93 Oct tune k&n filter tighter gapped plugs 3 bar map and downpipes catted, also from 2nd to 3rd gear just normal driving does anyone else feel a longer shift than the other gears? like it stays between gears longer before it shifts?

Okay I did thank you. It was almost like it was sputtering before it would shift and then shift and it'd come right back strong....I had put techron fuel cleaner in it last week don't know if that had anything to do with it, also notice a lot of black soot on the tail pipes

Do not use any fuel additives at all in your EcoBoost. Direct injection engines are very sensitive to fueling, and additives are the leading cause of fouling plugs, failing injectors and sluggish motors.

PS
If you are interested in "cleaning" your engine/fueling system just add a little really high octane fuel. You can add a COUPLE gallons of E85 or MS109 either will clean that baby right up!

Okay excellent..... Do you think I did any damage to the car it was only one bottle and the tanks almost out I'll refuel it to dilute it more....

How much e85 would I pump in after fueling with 93 what's your recommendation and how often?

 

[Livernois Motorsports]

Literally a couple of gallons would do the trick. @SHOnUup4 would be able to help you with frequency. He has it down pretty well.

I've been mixing 1.5 gallons of E/85 to 13 gallons of 93 (that has 10% E in it). You could probably use 1 gallon of E/85 and get the same benefits.

If you're in a colder climate, the car needs a good 10 minute warm up...that's idle in driveway, and then another at least 10 minutes of driving to get the trans up to operating temps. If the trans isn't warmed up fully it will hold gears longer in an effort to warm up the trans.

With the saddle tanks on these cars, to mix properly, ideally you should put in the gallon or so of E85 and then immediately fill with 93 rather than add the E85 to the 93 that is in the tank. That may not be so critical if you always run the mixture but for the first time, I think the E85 followed by 93 is recommended. Rich, do you agree?

 

[SHOnUup4]

I prefer to add it prior to the 93, but I have both at the same station. If you have to drive a few miles to get e/85 I wouldn't be to concerned as it will mix up after some driving.

I'd be concerned if I was tuned for a certain E %...but not being tuned for it I'd think it isn't mandatory.

It's still doing it it seems like it does it after I drive it for a while then floor it and at the end of each gear it like cuts out and goes on again then shifts..... Will it take a few tank fulls of gas to fix the problem? I really don't think it's a tranny issue....what do you think

 

[SHOnUup4]

Could be an injector issue that shows itself at top of gear where fuel is needed? Maybe even dirty MAP sensors.

I'm going to check the air filter tomorrow and maybe some map cleaner? It's so wierd the car doesn't do it sometimes only if I'm driving it for a bit and start hitting the gas hard from 1st to 2nd never does it if I kick it down from 40 I feel it about a thousand rpm before it shifts it like hesitate and comes right back and then when its about to shit at 100 I see the rpm get close to shift then go up and down slightly then shift

Are your plugs new and gapped correctly
