Chuck from HPE came out to Utah yesterday to do a group tune. My computer is pretty much maxed out at 4600 rpms so we couldn't run it up any higher but here are the results.

good numbers, more power to be had if u can rev it higher without probs. What kind of boost you running?

What is your fuel system??? What do you mean your computer maxed out??
That is awesome numbers for 4600 rpms. Tell us more about the setup, F1A right?

Boost is climbing upwards of about 13psi when the graph goes crazy but the few times he took it to 6000 it got up to 18-19psi.
I'm running 60lb/hr injectors and the Lonnies double pumper/hotwire kit and an AIS stage 2l kit with 100% meth.
He made 14 pulls trying to fix it and he said the VE and power enrichment tables are maxed out and he can't add anything more at that point and he said its pretty much at the limits of the stock pcm?
I'd like to get this figured out because I see atleast another 100 hp easy on a full pull!

It will be more than 100 hp, that would only be D1SC territory with your 6-speed and F1A that would be a whole lot of power . going from 13psi to 19psi would net BIG GAINS, epecially if the tuner is really using the alky kit you have to tune it.

MAF tune or speed density? Something is not right??

Funkybird

iTrader: (4)

I agree! For the first few pulls we were using the MAF so he switched to speed density hoping to be able to fix it. He picked up quite a bit of power but never could fix the top end.
I am on the stock map sensor though? I wonder what would happen if I picked up a 3 bar?

T/A KID

iTrader: (12)

Lt1 computers can't do a 3 bar without an aftermarket ECU, some guys have done 2 bars though. You need to get into contact with Ed Wright IMO.

Nice! What part of UT? Haven't seen your car around here so I know you're not a base rat like me

Funkybird

iTrader: (4)

Actually I work on base and I live in Layton. What do you drive?

I'm going to agree with needing to contact Ed Wright. I think he could sort out your problems. That thing is going to be a beast when you solve the last little gremlins

Update! Finally got around to swapping out the tr6's for some tr7's and lowered the gap to .025" and I took it out and ran it up to redline in third and it felt great! Gonna get on the dyno soon and see what happens.

Update: Just got home from the dyno. I messed with the tune a little bit and I was able to pick up 100 more hp. The bad news is its still running out of fuel and the fueling tables are maxed. I have reached the limits of the stock pcm it seems.
This is on 91 octane.

congrats Randy, put down some great numbers, I hope to put down close to that, just have to swap out the 60# injectors since I already maxxed them out.

Funkybird

iTrader: (4)

Thanks! What injectors are you going to go with? I'm running 60's

When the graph cuts off your just at the 5250 hp and Tq curve. Reving the motor to 6500-7,000 depending on your pulley setup would probably net 900RWHP if you had the Fuel.
In my opinion its not a PCM problem, but something else????
