Unhappy LS1 Boggs when given throttle...UPDATED WITH VIDEO INSIDE!!!..PLEASE NEED HELP!!!

Ok my car starts up fine everytime. NOW when I give it some gas (throttle) it wants to die out, then if I let off and catch it.... it will go back to idle and be ok. Now it did this with my ls6 intake and 78mm t/b combo as its doing it with my new fast 102mm combo...SAME IDENITCAL THING. Thought maybe the swap would take care of it...WRONG!!!

Now I notice WAYYYY more raw fuel smell and makes my eyes water. I also noticed this: When I unplugged the Intake Air Temp sensor (IAT) it seems to be more responsive on the throttle side, then when plugged back in it sounds like its not getting fuel or like choking out and stumbles and can die out or real close at times.

I replaced the IAT with a new one and still same results.

The car is tuned with a SPEED DENSITY TUNE so no MAF Sensor.


I need some LSx Master Techs input what to look at, where to start,please help

Here is the video, and yes I know there is no coupler in between the t/b and lid it did with it on or off. and also everything its doing with this 102mm setup it did the same stuff on my ls6 intake 78mm t/b setup also.

What about your TPS sensor? Did it get transfered over to the new T/B?

I just replaced it last month, and I also don't think it would be the fuel filter as when I disconnect the IAT it responds good.

I think its a sensor just don't know what one and where to start.


But I'll check it out, I do have it on jack stands right now and changing a fuel filter is only 5mins and I have my old one which was good also.

Well I have made some changes should see results in 1-2 weeks, I'm looking forward to results. And its not about dyno numbers to much, as the Track Numbers matter most for me and the car is running good. If I lose 10rwhp but gain .1-.2tenths in the 1/4 mile and car runs better I sure in hell will take it!!!!!



Until then........................

Well I decided today to check all my sensors that may play a roll and also check my pcm.



1. noticed two plug in sensors had water inside the connectors.

2. noticed when I took off the red and blue connectors to the pcm look like a few pins were either corroded and burnt, how IDK? I cleaned those up.

3. reinstalled all sensors and connectors.



and this is what happened............

working good now, went down the streets and lit the tires up pretty good.

But i'm still waiting on a few things to come in and doing some upgrades not for HP but for better driveabilty and tuning. and then the new tune.
