I went to REM and Paul tuned my truck for a little while and this is the best combo we could get......


What's holding the horsepower down? I've got very high torque numbers but why is my horsepower so low. I was expecting aroung 10-15 more hp. But overall i'm very happy .This is on a Mustang dynometer. I've been told that this equation will convert your numbers to a Dynojet....
(Mustang HP X .9) / 2615 + 1 X Mustang HP = Dynojet HP

*EDIT*
My mods are
2# upper
4# lower
Filter kit
90mm mass air
Ported Plenum
Borla Catback
Factory Tech valve body/ tranny pan

 

What were your a/f ratios? Are you tuned really 'rich'?

Dan

 

Not sure...didn't get that printout, i was tuned really rich, but I'm sure it's within the normal range, 11 to 1..........

No one else???

 

Hey Brian,
I had the white supercrew that was at REM today.Did you notice on the graph it only showed up to 4500 rpm's.My graph did too,which would explain only 8-8.5lbs of boost.At 5200 rpm I normally see 10-10.5lbs. My max hp @4500 was 293.1 at the wheels.Is 293hp enough to push a 5500-5700lb truck 13.9 in the 1/4 mile?? Seems weird.

See you around,
Frank

 

I had my truck on a mustang dyno with my REM diablo chip, a 5lb lower, and ram air setup. I made 401.2rwhp and 461.8rwtq. According to your equation that's 456rwhp on a dynojet.

 

See, your almost have the same mods I do, and your making 45 more hp, but 30 less torque, uh, why

 

Could have something to do with the rpm readings, mine are at 4750 and 4500 while yours are taken at 4250 and 3000. I would give Paul a call, I'm sure he can explain everything to you, he's good at answering questions...smart guy Paul is ....JR

 

Oh, i know, been there a million times, it's not that he didn't make a big change in my hp and torque. I gained 20 rwhp and 70 rwtq by just putting the truck on the dyno and having him tune it, compared to the mail order chip. I can't believe the power this thing now has. It's a whole new truck

 

Hey Brian,

Nice numbers man. Im sure you thinkin the numbers are low is because of the Mustang Dynometer...

-Mike

 

It's 10.30...and I'm too tired to give a long explaination, suffice to say there is a very good one and it has to do with the test procedures that I as a tuner prefer to use. I'll post an answer for you all later...For now, just ask Brian and Jon how there trucks run
Paul

 

My truck runs awesome, thanks to Paul......tracke are closed for the winter, but I'll be ready for spring......deep into the 12's are on the way...........
