went to the track today and wasnt exspecting much. threw a whole bunch of new parts at the car. its a whole new combo. most recent additions are a double pumper seet to kick on at 15psi, 72# injectors, a ramchargers modded ecm with ME-16 pos. so anyways it only ran a 12.4 at 107 with about 17 psi boost on street pos 4 and 40 psi line off. it lightly popped all the way down the track and was way rich. no knock at all. i had a 1/2 mix of 94 and c-16. i then tried a race setting and it popped even worse and i had to lift but still no knock. i dont think i did the offset thingy right, as all i did was plug in the chip and go, i really dont understand how to use the offset feature.
