Thank you for replying, No we cant see the pressure while pulling just have a small gauge under the hood. after it warms up a little you can get it to start fluttering while setting still, the pressure is not dropping while running the throttle under the hood. But it still has that fluttering around 3500 on up, I've got some bigger jets on the way and my friend has a magnafuel pump that we are going to try. Hopefully I can see something change, either get worse or get better, everything I have done has not changed anything even a little, So we'll give it a try and see what happens.. Thanks again, I really appreciate the advice!!
