It was a dynotune. They did a total of six pulls. The first pull 360 HP and 444 TQ. and the last pull, after tuning was 406.9HP and 489 TQ.
Are those numbers even possible with the mods I have??

 

There are people with 4lb and 6lb pulleys that don't get those numbers. The only way you'll ever have a number you can compare to others is to do a pull on a Dynojet dyno. Try to find one.

I know, I know, you can compare with a mustang dyno too, but while they're great for the load tuning who wants to look a low number?

 

I got 409/520 with a 4.

 

Very nice numbers Leanne

This post appeared on another Lightning forum today:
I'm just saying there are people that have way more mods and boost with less power. I suspect the above poster has a bad tune to be honest. But still, get that truck of yours on a Dynojet so you'll know for sure.

 

Biding that you are not dynoing when it's 90 degrees out, just about any tuner with any kind of knowledge should be able to get these trucks into the 400/500 club on a 4lb lower.

There was a kid at the track last week with a 4lb lower, 2lb upper and more crap then I had running high 13's. Said he dyno's at like 370 and 460 on a dyno jet. Mail order Diablo tune. I told him if he didn't see at least high 12's and at least 410/520 that something wasn't right at all.
