Has any one had this issue?
Car is a 16 Mustang manual with Edelbrock 2300 supercharger.
When on the power up in the revs its great but low down normal driving it can be quite a pain due to the throttle.
Best way to describe is when in slow traffic or when you have lifted of to coast then go back on throttle lightly it will jerk forward like you have dropped the clutch.
Where do i need to be looking to try and resolve this.
New to HP Tuners so be gentle.
Thanks Craig.
need to post a tune and log, at very least a tuneQuote:

Just been out for a drive and took a log.
wasn't as bad today but it is the first time driving it since going to the VMP AIT sensor.
Normally it feels like you have been shunted as you go back on throttle after coasting or after a brief lift off.

Who originally tuned it?
I haven't looked at the files but I'd bet you need to look into your torque/inverse tables. Are running 0-25 or 14-25?
In mapped points config it is setup to only use mapped point 14.
This is the stock edelbrock tune.
The other tune is the same.
I know Roush use 14-25 i think and stock 0-25.
Using only one MP?
That is the epitome of a lazy tune!
Out of all the tables 14 is the only one that is different. every other table on the torque calculation are identical to each other but they are all different from the stock tables.
I expected all the rest to be stock and just turned off but they are different.
