tfi upgrade

[Blackstallion8]

hey, its been awhile since my last post! sold the cobra two yrs ago. built my house as planned but now have some regrets selling the cobra??? weird! lol... the new owner has it puttn down 590 rwhp now!!!! thats another story tho.

gotta pick up where i left off on the fox. been thinking of upgrading the tfi module with one that claims more dwell time. Dyna mod is the brand. i was told to gap my plugs tighter because maybe boost was blowing out spark?
im only running 4 lbs of boost had issues before with it bogging and falling on its face at 5k at the track.

The Screamin Demon from Performance Dist is the one your talking about, never really had issues with the stock TFI module but those guys at PD are class acts.

Typically unless your ignition is weak 4lbs wont blow the spark out but I would gap the plugs down to .035", and think about a good tune up with decent wires (I prefer the Taylor pieces), new dist cap and new plugs (1 heat range down won't hurt), a good coil.

Whats the exact combo you have?
