Switching from Fuddle to a Yank ,What to Expect.
Switching from Fuddle to a Yank ,What to Expect. Ok here's the deal I am now running a Fuddle 3400 2.1STR,For $350 its done an awesome job,But Im looking to step up To a PT4000 from Yank.The Fuddle has good drivability,Nice smooth Lock up,And has Netted Me Consistant Low 1.6 60fts and even a few 1.5's.But Im concerned that the Fuddle isnt all that Efficient ,I dropped 3 tenths of my E.t but Lost 1-2 mph in the traps.Im currently Running 3.42 Gears Which I dont wanna change out.Im thinking about running a small shot on the car when/If I get the PT4000,But the car will be N/A 99% of the time.What Kinda performance gains should I expect Switching out the Converters,Would this Be a good move or should I stay with the Current Stall,How would the car differ from a Roll?Better?Worse?How efficent is the PT Series?Any Info is Greatly Appreciated 
Not sure bout the PT series Yanks, but from a 3600 fuddle to a ss3600 Yank was a huge difference. Really not much different in cruising or the "hit" between the two, but "PULLS" much harder up top in 2nd and 3rd.
Here's some info on the PT4000

i pulled 1.75-1.80 60fts with the converter and gained about 3mph in 1/4 mile, but i have mickey thompsons now and want to pull 1.6s and keep my top end pull or improve it if possible. the PT4000 sounds right for the occasion as far as i have read.
