Hey guys,
Got a Nag1 5.7 challenger with a TSP Stage 3 cam and long tubes.
When launching the car from idle-1500rpm it falls on its face up until 3k-ish RPM and picks itself back up. Any remedy for this? Torque management issue?

heres a log. towards the end you can see I go WOTrev_21_v3.hpl
what converter are you running?
Stock converter
Thats a pretty big cam for a 5.7 and stock converter in a nag1. You defiantly lost some low end
Thats what you'll get from a stock converter, you need to get a 3200+ converter so you are more into the power range. The came may make good power over stock, but at 1500-3k rpm you'll lose alot over stock also.
I figured i needed a TC but was also since the cam is a boost cam i was hoping when i add a magnuson blower that it picks up power down low and across the whole rpm range of course.
Guess I just wanted to see if there was any problem with the tune before throwing a converter in.
Thanks for the reply guys!
The blower will certainly help but you will still want a converter. Being a roots style blower you can get away with less converter though
I ended up changing some Torque Management tables and was able to feel a difference down low a little (pedal % and power % tables) but im in agreement about getting a TC. Was thinking something around 2800-3000 since ill be doing a roots blower. Also kinda stuck on the fence about centrifugal but id just go up in TC. Also these 3.06 open gears gotta go. Thinking of doing 3.09 LSD
