Have you taken your car down the 1/4 mile? If so what MPH did you run.

Hasnt been on the track yet. Probably wont do so until I get the longtubes installed.

Make sure you pull the 50 amp fuse for advance track when on the dyno.

Yea yea, now you tell me LOL.

So, now that I have a Lund tune for a stock car with the catback, I'm tempted to toss the stock intake on for a dyno run LOL. Cost me $125 for the shop to swap intakes while its on the dyno but it may be worth it for giggles.

Those numbers look about right... why disappointed?

It is easy to swap the intakes. When I was having issues with mine I could switch them out in 20 minutes or less.

You see the little lines at the bottom left corner of the dyno sheet? THAT's why. He put on the new intake and it ran like shit with the tune, so they basically didn't bother making a pull. The 401 was stock intake and the canned SCT tune, I believe.

Problem is I'm not permitted to do any work with it on the dyno. I can make the first two passes with the stock intake and pull it off the dyno but then I have to pay for another dyno session. That may actually be cheaper now that I think about it LOL.

Yes, stock with the exception of the catback and the SCT preloaded tune. Worst part about the situation is that was my own fault for not including the information about the JLT (just assumed it would be accounted for since I ordered the JLT/SCT/Lund combo).

On a positive note, I just received the updated tune from Lund. Cant beat that for customer service!

Considering you just got your tune revised are you planning to take the car to the dyno anytime soon? Would like to see if that issue gets resolved.

I scheduled to go back Monday afternoon but I cancelled; didnt want to tie up the dyno if I didnt have a fix. Provided nothing got rescheduled this evening, it will be returning on Monday like initially planned.

 

[madweazl]

Running much better. Not perfect but so much better than before. I'll try to get a good amount of time behind the wheel before Monday so the computer has time to make some adjustments and hopefully all will be well.

Biggest issue I noticed was a lot of surging at lower RPM and part throttle (20-50%).

Pull the advancetrac fuse as Vinny mentioned and your problems should go away.

Why would pulling fuse help now? The Advance Trac and TC lights went out as soon as the car hit solid ground after coming off the dyno and havent come back on since.

 

[phunk]

I have been on the dyno 3 times and do around 10 pulls each time. Sometimes back to back, sometimes I turn it off and cool for 10 min then fire back up.

Never had to pull a fuse personally... and my numbers all seem right where they should be.

 

[madweazl]

Oh, forgot to mention that the exhaust is even louder now. Has a much more pronounced crackle vice the rumble it had before.
