Default 4k gov springs = SUPER touchy throttle

alright guys i got my pump all back on and installed since the 4k gov springs (it was installed and recalibrated at industrial injection) and now my throttle is ridiculously touchy. i live on a long dirt road with a bunch of pot holes and it feels like im learning how to drive a stick all over again now its not very fun to drive.

what can i do to fix this? i already have a pretty tough return spring on it, any ideas?

Good advice. The 12v is all in at 2200. Spinning it over 3k is not doing much.

most guys on here go with the 4ks so i dont think they are suppose to be "touchy", i think i heard somewhere on here that if something is too tight they will be like that, maybe someone knows what im talking about and will chime in or correct me if im wrong

^4k's are touchier than 3k's by trade. This is normal

if i were to do that would i need to recalibrate the pump again, because i dont want to have to do that.

and is there another way to help it out a little bit? like maybe more return springs or anymore tricks i should know? thanks

Like I said, 4k's are VERY touchy and fuel hard as hell. Thats the nature of them. thats why people get the 4k's. Most people dont spin their motors higher than 4k... or anywhere close.. they like these springs because of how responsive they are and how hard they fuel.

you dont have to get the pump recalibrated if you take them out, all tho most people will say that is the "right way", i think almost everyone on here would throw a set of 3ks or 4ks in and not think twice about recalibration
