I'm running a Racetronix pump kit in my 92.

They make a good product.

Not trying to be mean, but doesn't buying something and then asks if it is good kinda dumb, don't you think.

But, it is a good product and I have been running on mine for 2 years now.

Racetronix does not make the pump, it is made by Walbro.
All they do is package it with install pieces.
No instructions included.

I have a stock GM pump for a GNX in mine. Dont ask me why, but I bought it years ago before I knew there was a Racetronix/Walbro pump. I am pushing 500hp. Maybe I need to upgrade and see if I am missing something.

Fuel pressure on the Dyno kept dropping down to ~35lbs during the pulls, and that was with pressure set at 52lbs, using the stock fuel pump and 42lb injectors on my 383. Once the stock fuel pump was pulled and replaced with the 255gph I had with me, Ed cranked down the fuel rail pressure and then subsequent pulls showed constant pressure with no dropouts throughout the pulls. Will didn't experience this because he changed his out to the HP Pump before we went to the Dyno, I had my HP Fuel pump with me but didn't change it because I thought I could get away with the stock unit.................I was Dead WRONG!
