Hey Bud, I am the guy that sent you my Accel dfi for repairs, hopefully you can get er done, i have the most faith in your work, as i have read several other posts commending the work you do, anyways, i know if it can be done, your the man... ok, enough brownnosin, lol, but i have an oppurtunity to purchase a Jacobs Pro Street Ignition, i guess enhancer, plus an Ultra coil for what i have been told is a pretty inexpensive price of 175.00 Do you know if i can incorporate this into my system that i have told you i have, or if it is even worth my time,It has been running on a 7.4l just like the one i am running, and to the best of my knowledge, i have a stock coil, so...should i stay or should i go for it? haha. my setup, in case you dont remember is a 1991 gmc sierra, with a 1998 7.4l 454 out of a suburban, it has a pretty radical cam from competion cams, not exactly sure of the spec.s headers, 2 1/2 " flowmaster exhaust, An accel gen 6, (praying it can be fixed by a new friend)but the distributor and coil, im not too sure of, possibly an accel distributor, with an external coil. Will it help? the guy told me to set up the dfi to only control the fuel, and if i buy this thing, to let it control the spark, timing advance, etc. good advice? waddya think pro's out there? help a newbie out. I'll be lookin for a reply, he wants to get rid of this thing soon, said he invested over 400 in it, barely used it, sold the truck it was in,so he pulled it out. Talk to me, Lust 4bst...thanks guys, o yea, it evidently used to be a vortec setup, but now its multiport fuel injection, not too sure of all the differences, but it screams, well it did for a little while anyways.
