Another vote for Thumper carbs.........

My Prosystems carb tune was out to lunch....even though I filled out one of there sheets and gave them all the info.....Tune was real bad. I spoke to him couple times, seemed like a smart guy, too smart for a simpleton like me to understand. I gave up on dealing with him. We had real good luck with Proform race carbs, so I looked up their jetting, basically the same size....Put all that in my carb...ran like a scolded monkey after that.....Tuned it in and ran for many years. Lent it to a buddy of mine that was having trouble with a brand new Quick Fuel carb, and he picked up over 1/10th.....He wouldn't give it back, so I sold it to him, and this began my relationship with Thumper carbs.....

I say relationship because we still talk ever other week or two about the tune in one of his carbs I have. With his, I picked up even more ET and more MPH.....and he helps get the tune where you need it...THAT's Service! Although I think Mopar Dave there is out spending me by a bunch this year...I have been real happy with mine.
