oh yea totally!

i kinda know, but I think optispark is a total piece of shit that connects the distributor and GM was really intelligent b/c they put it beneath something that can leak water onto it...HENCE it dies quickly.

ahh gotcha... thanks!

its a pain in the ass from what i have heard, and yes it is the ingition system like the coilpacks on the LS1 cars, sorta like the Distruibter

The optispark IS the distibutor. Is uses a plastic wheel inside of it with 720 tiny ass holes around the perimiter that an infrared eye sees through to time the spark to within half a degree. You couldn't stick half a tooth pick through those holes they are so small and when one gets wet or dirty at all there goes good distributor functioncause the eye can't see through it. Top that off with it being mounted UNDER the water pump. . .you get the picture

anyway, it's an LT1 thing, and most of us were smart enough to buy no LT1 cars

forgive my ignorance but did you say on his mods that he deleted his maf sensor? what is the purpose of that is seams like it would hurt performance. or did you mean the free mod with the resistor wire in the intake air temp sensor? or perhaps a aftermarket airfilter or screen delet on the maf.

MY MAF is also deleted, but i had a tune so did he.

soory but i am failing to see how this would help performance as this is a needed input for the ecm to correctly calibrate the fuel in diffrent driving conditions. please explaine
