I'm finally getting to the point where I'm able to spend some ca$h on my truck. Included in the future plans are RV275 injectors and an EZ Box. I'm not looking for big numbers out of my engine - just a decent increase in torque/power. I've heard very good things about the 275/EZ combo.

So the 275 injectors advertise ~40hp increase and the EZ box advertises a ~60hp increase. So when you put them together, is it purely additive (~100hp total) or somewhat less? Not that it really matters - I'm not planning to dyno my truck. I'm just curious what kind of power bump each one is going to give me with respect to the other.

Thanks for any info.

I've got that combo, but have never dynoed. I've heard it's around 300 rwhp and over 600 lbs of torque. Stock TC might not get it to the ground though. I've seen where just a TC upgrade will net around 11 hp over the stock unit. If all this is true you should be in the 290 hp range, with a upgraded TC you'll be over the 300hp mark. I'm running this combo thru a mostly stock tranny, just a shift kit.

I was able to slip the stocker converter with the EZ and 275's combined.

So far so good with mine. The 275/EZ combo is a work of art.

I have that combo too, runs great. A small improvment in MPG as long as I keep my foot out of it. The stock clutch cound't take it though, so I installed a SB CON-OFE.
Oh yeah, I have dynoed mine, 310.4hp, 772.8lbft. My truck is an HO, not sure if SO or auto guys will see the same power, but should be close.
Enjoy!
