The truck pulls HARD in first, shifts good and when the truck gets to ~4100rpm in second gear, the the blower sounds as if it's slowing down. You can feel the accerlartion slow and then pick back up. After ~1.5 seconds it picks back up and pulls hard again. Anyone know what this is?
You can hear it at ~4.5 -6 seconds in the video.

BTW, the mods include a JDM chip and open element filter. ANY advice is welcome. Thanks.

E-mail me at dhco@rcn.com

I have a answer for you , so send me a e-mail and I'll give you my number so I can explain it to you

 

shouldnt your truck run that time without a chip? sounds like there is something not right with the chip?

 

It was 89 degrees with a ~5-10 swirling wind. It ran a 13.55 ealier. The engine only had ~20 minutes of cool down time.

 

Cornercarver, You explained my runs exactly. I never looked into it because I'm running good times. I also thought I must be lifting on the gas during acceleration. See my sig for mods and times. Anyone know the answer? If you want e-mail me at qcaptq@aol.com
Thanks. Dennis

did you unplug the boost selanoid? You may be reaching max boost and the bypass might be opening up.

 

Don C, Thanks for the reply. No I didn't unplug the boost solenoid. I don't know how. Is it in the faq? what are the pros and cons. Is it safer leave it as is? Any other suggestions welcome. Thanks guys.

 

IS it possible your bouncing the rev limiter or its possible the transmission fluid is too hot cause a low boost condition?

 

Could be torque converter lock up.

 

Good questions.

 

If anyone can give me a solution I will give you the rest of the week off from work. Plus you can go to the most expensive steak house in your area, mention my name and your in like Flint.

On the drivers side of the supercharger , close to the firewall there is the boost selanoid. It looks like a little black beer keg with a metal rod on the bottom, and a plug on the top. Just unplug it before you race, when you are done racing plug it back.

Also if you have a 2001 turn the overdrive off. Then mash the pedal hold it to the floor and have fun.
