TQ guys - sec jet mod

Rat,
Haven't seen those mods before. What DOES work & is much easier is the sec mods under my name in Oct 23. PM if you want more info.
How good is it? 3900 lb [ without driver ] Pontiac 455, 3.31 axle T400, 850 Chrys TQ ran 11.7/119, 11.6/118, 11.5/117 mph at Eastern creek. Inexperienced driver & NO tuning done at the track. 850 rpm idle, factory power brakes.
