Stock Fuel Pump?

Can it handle the Shot, cus we have been having issues with lean spikes and it can only be due to weak pump, but only tuning with a 75?

Who has the stock fuel pump..

how long is the lean spike? are you dry or wet?

there are lots of people with 75 shots up to 150 with the stock fuel pump.

My stocker handled a 150 when I was just bolt ons. Throwing in a $100 Walbro is never a bad idea though. Yeah, give us a little more info on your setup too.

Fuel pressure would be the best bet of how the pump is
