Went to the track tonight my times were horrible

[IdahoRob]

I have a twin LMM working with right now. Running 45lbs of boost and high egt's. Fixed the boost leaks and still has the problem.

I received a log and looked like the converter wasn't locking. I had him manually lock the converter using efi and the problem was gone. Boost went up to 60psi, egt's dropped 300+ and added a good 75+HP. Repeated time and time again.

Just from a weak converter.

Logs tell the truth and take away internet guessing.

Well put Rob

I beleive if you have your big tune on the default setting than you have the ability to change all tables. Thats where mine is set.

I'm in the same boat guys. Although mines stock turbo and injectors, I've got all the rail pressure ill need. And a good working cp3 in the stock trucks seems to be the difference in 12 and 13 second passes. High1.8 60 is all I can do. With 285/75/16 all terrain at 45 in front and 30 psi out back. Caltracs etc. My beat with the new setup is 12.97 with all runs in th 102 mph range... really sad to see stock motor trucks running low 12s when I have a lot more invested in go fast parts. Not sure if this is important or not but I'm not seeing over 30 psi in boost till overdrive, underdrive is about 26-27?

whats your weight?? I had a huge boost leak the best I went full weight was a 12.32 which is pretty good considering... but now shes lifted sooo that will problay be the best till i build the motor

idk i had the spare on, with the tail gate and a buddy in the seat last time i went. about 1/4 tank iirc, and jackets other hunting clothes in the back. Just don't see how getting a better 60' will greatly improve my time. I have seen people get horrible 60 times and still have good mph, i just think my truck must be underpowered or something?

 

[BUST'EM 504]

been in the same boat but weight will greatly affect your times. every 185lbs is about a tenth and every tenth off your sixty is about two tenths maybe a little less in the quarter.

sorry for the highjack, nowI see the original date though and don't feel as bad lol. But I sure hope your right about the weight thing. I went 12.85 earlier in the year, holding 21,000 psi, and now holding 26,000+ I am going slower. I have picked up 1 mph and that is it. btw I think I was at 1/2 tank actually with the 26 gallon, so roughly 16 gallons of fuel)

 

[BUST'EM 504]

your weight is a huge factor

We should go tomorrow night:thumb:

hey you did better than me. my first time out i ran 13.466 @ 104.82 60' was 2.225 and R/T was .759 i need practice bad plus the truck weighs close to 8k and the tires were at 65psi with a 5psi launch in 4x4... i did everything wrong but the trap speed was good. next season ill be spending a lot of time at the track and dial it in should be in the 12's with practice... what do you guys do suspension wise??? clamp the springs, lower the t bars, tire pressure, etc.

 

[Jscherbs]

lower those tbars and tire psi. 32 ish in front and 28 in back w/ clamps on the front of the spring pack seem to work well for most. leave from 15-20lbs of boost and hold on.

I hope you're joking.

He means he full flashes back to a single tune OS. A lot of guys do this because there are way more tables available when in single tune form. I'm gonna try this next time I go back.

There aren't that many tables availabe in single tune form than there are in DSP5 form. Also any tables that are you can change to whatever you are wanting before you converter the tune to a DSP5, then converter and save it, then open it and put in the tunes you want.

Slap some Caltracs on it and try launching for a day. You will feel the diff and what the hell the price is right what $200 or so. Cheap help if you like them..........
