Help!!!

finally got my 4.6 mj running after sending it to the shop, now im having an entirely new problem. i have this engine a little hot with 24 lb/h enjectors from venom racing, built a map adjuster from a schematic found on angelfire.com which seemed pretty legit. the truck sputters at about 1800 to 2k rpms when running, hoever if you give it a little extra gas it goes and continues to go as long as you dont let off the throttle. tried to adjust the fuel curve with the adjuster and now my problem is when i switch on the map adjuster the truck rolls over and sputters but wont start, even when set to the stock voltage. im not sure whats going on, maybe the adjuster is messed up or whatever, either way any suggestions will be much appreciated.

Something tells me you would be better off posting in a strokers forum. The knowlege base here is already thin for the stock stuff, let alone something as technical as a stroker.

i agree with what is said above, far to technical for most of us.

but as i am about to build a stroker my self where did you find your parts (i.e. crank and pistons) and (if you dont mind my asking) bout how much did you spend on your stroker?

thanks
