ok i got a new tune from wheatley its tuned for 28" tires but i am temporarily running 30" could this be the reason its nor running right like it shifts hella slow and is not pulling that hard.... what do you guys think

 

bigger tires for one,do you feel it shift to early?

 

no its not to early it just feels like its taking a long time. could that be due to the tq managment that you took out? i just drove it around for awile it feels strong! runing good now but the shifts just feel slow its shifting at the right rpms weird but its fine. just slow

 

after my tune it shifts much quicker, did he up the line pressure? could it be a bad computer?

 

Mine shifts very quick and firm.

 

Try taking the trans settings off the old file and comparing them. Like line pressure, shift time, etc

Wonder how many trucks Wheatley works on daily...

 

i had my tune for 28" tall tires, those are my drag radials, i run on my 20's daily and they are 30, no probs here, runs hard, shifts hard and fast

 

my tranny shifts slugish as well after my tune from a different tunner, I bought EFIlive and a tune from him but the tranny just seems slugish

 

Servos and a lil work on the trans settings and you wont be complaining..

 

You know I did not even think about servos
