I have a motor that has 243 casting heads, a TR230/224 cam and it won't run right. It idles erratically, surges, smells like gas and has a mild tick I think.
When you put the motor under a load in first gear then put the clutch it, the rpms drop really low like it's going to die.

Compression check, fuel pressure test and vaccum test all checked out so I figured it must be something in the tune.

any help would be greatly appreciated.

 

what software are you tuning with?

 

HP tuners.

 

Have you tuned it yet?

 

Yes it has been tuned by an experience tuner. The motor was swapped to another car and is having some issues getting it right.
