Default HELP! Where is my hp?

On a dyno jet I made 380hp and I don't know how much torque. I've asked them twice to email me my dyno sheet and I still haven't got it yet. Mod list

230/230 .613 .591 111+2
TFS (as cast) 220
LS6 intake
Qtp lt's
Ptc 3500 stall
Slp lm1
3.73
Lid
Walbro 255

What could possibly be holding me back?

Stock injectors? Car throwing knock sensor code? (I don't know if it was on the dyno as my tuner didn't say anything but my light was on and the next day orielly code reader showed it). I'm running the shim / pushrod kit from thunder racing and maybe I goofed something up there? I really don't know. I'm no engine building expert so I'd like some advice from you guys. Car ran 11.6 @ 116mph w/ 1.6 sixty.

I'd say the stock injectors are holding you back some.

The shop should be telling you. They are the one's dynoing it and hopefully scanning the computer.

They told me my injectors were at 90% but my car needed an intake and I'd break 400hp. I just figured a h/c car would make 400hp through an ls6 intake all day.

It should. The majority of cam only cars are putting down 400 or north of that. With those bad *** heads and that cam, you should be around 440 to 450.

Whats the DA in missouri? Does he have a similar car to compare your numbers to? Was this # Locked? What correction?


IMO you should have maxed those injectors out.. Is this a well known tuner?

The injectors should be holding the hp on the dyno just fine.

Is the converter locked?

Yeah, I'd like to know who the tuner is as well. I'm in Missouri also and don't want to go with someone who doesn't know there **** or is unproffessional.

Im not sure the DA but it was 90* that day. Converter was locked I'm assuming since he didn't say any different. He tunes alot of stuff that make tons more power than mine. This was through a 10bolt.

Mid 11's on motor is all you need to know - the dyno could be a Mustang, it could be very stingy, or it could be completely off. You're making great power on motor.

Well it was a dynojet. I originally thought my et was decent, but then I got to thinking there are cam only cars making the same hp running those numbers.

I ran an 11.5 @ 120 with 1.7 60' in 2500 DA with 480rwhp - some of it's the setup (getting it to the ground), some of it is driver, and some of it is power. The Cam-only cars running mid 11's could be stripped out race buckets like some guys I know, or maybe they just found fantastic DA... can't really say.

This makes sense now. He probably had to cut your tune way back for the nitrous because you are on stock injectors.

I'd figure he would've told me that if that was the case.
