Huh, I didn't know that the GMTU limited 1st gear...
There's really no way to limit boost, as our ECM is totally torque based.
By that, I just mean, that you can't set, a numerical boost limit.
That being said, by limiting torque, you are limiting boost.
Stock 5sp 1st gear is torque limited, starting at 1,000rpm, by only allowing
51% of available torque, & slowly increases to 63%, by 4,000rpm.
So a rough average of only 60% of available torque, is allowed in 1st gear,
with should really work out, to more than just 5psi, on a stock "tune" ??
Most tuners give you 100% of available torque, all the time.
I can see where limiting torque, with street tires, in 1st gear, with a 5sp, could be helpful.
But, I belive that you said that you were going to use slicks at the track.
If so, ask Vince for a track "tune", that gives you 100%...
This way, you can load your track "tune" in your ECM, before heading out
to the track...

I would never reduce operating engine torque as you can never have enough torque...

Got er strapped into the dyno again after the update: 331HP 407TQ
This was at a local street racing event(legal). Pro tree 1/8 mile, stop light drags, and roll racing. I'm happy to say I went undefeated in roll racing.
Here are the victims:
Early 90s ford thunderbird- no competition
Late 90s pontiac Grand Prix GTP. Fully bolted and tuned makes 325 whp
Chrysler 300 with a procharged & intercooler Hemi V8
2011 Subaru STI hatchback, fully tuned, and some other unknown mods(best race of the night for me, very close and I came from behind for the win)
Hit a new best 1/8 mile time of 8.91 @ 86 MPH with a 2.3 60ft. I need slicks bad. No street tire can handle the vicious spool of our K04 on E47.

A good E47 'tune' , will always put you over 400 TQ , A buggy on steroids...
Vince did you right…
It's always hard, trying to tell guys, that E47 makes our buggys a torque monster...
Yea, 400 TQ , with wrong-wheel-drive, SUCKS...
Slicks + 400 TQ = 12's...

Good to see you guys are still making tons of power on here I still come in and read up when I can.
After receiving a bunch of advice and info from 2005hhrauto
I was all set to buy hptuners software early spring
Unfortunately my gas station that sold e85 that is 30 minutes away stopped selling it.
now its over an hour ride.
But my local speed shop just started selling e85 racing fuel made by renegade I believe. It has picked up a friend of mines car I help tune almost two tenths over the e85 at the pump.But they charge like$10.00 a gallon which is ridiculous
Anyhow got involved working on my drag car/street rod .
Then got the bug to buy a new mustang gt
Really need to get that 2005hhrauto tune
loaded.
