ever consider a shift kit? I had one in my 02 Lightning and it worked real well at wot

 

Its not a tranny issue!
the tranny shifts great with diablo's perameters

 

i'm a girl what do i know lol but on a more serious note ..there is a fantastic older mechanic in sherwood park who has worked on mustangs for years if you ever want to call him let me know. He will try to help out

 

i wonder if its at fuel problem too much at wot maybe?

 

PROBLEM SOLVED thanx to the boys and girls at Gotstang who led me in the right direction

 

Well,what was the issue??
Could be some good info here!

 

"the diablo tune ads spark advance and removes fuel in the 4-7k rpm range"
so i added 8 points of fuel and bang she pulls hard now all the way i put my 70mm TB back on and bam shes a wild machine now!

 

Nice!!! Glad you got it figured out!
