I have a thrasher, 237 fpr,k+n filter, and flowmaster exhaust. I have been leaning out and have minor knock. Does anyone know about the ty/sy pump and is it a good upgrade for what I have. I plan on a few more boltons, nothing big. Please tell me alittle about this in caomarision to the 307 walbro. Thannks.
