It's not needed, I've made over 500whp on the stock tb. LS4 tb is good, but **** for driving in traffic.

 

Get STOP mounts from TTR. That'll get you your power

 

The reason I wasn't making good power is because the MAF was turned off on my car. The car was basically running a VE tune, and it wasn't doing well at all. How do you think that happened Wicked?

Needless to say I had somebody fix all of that for me

 

Was the tune setup that way? Or possibly the MAF being unplugged/dead are only two ways

 

MAF wasn't unplugged and is working just fine right now.

If it was set-up that was, it wasn't by my decision. I didn't know anything about it until after like 5 minutes of data logging the tuner was like "You know your MAF is off, right?"

"Uhhhh......."

 

you guys arguing over the LS4 TB are making some very inaccurate statements. It isn't goint to hurt power, maybe drop a few hp for Peak numbers, but who really cares? The power under the curve will be quite a bit better, you'll feel the gain down low.

As for the OP's dyno being so low, it could just be the dyno itself, or it could be a number of things. Restrictive exhaust flow at the header/dp, need more cooling mods, better tune, etc.

 

Or it could be that he was not using his MAF and was using an untuned VE table somehow as stated by the OP a few posts above yours

 

that would be the problem right there, but I did say "better tune" lol.

 

It could be your intercooler pump. come on guy's it disturbs me that no one ever brings up the number 1 problems with these cars. your IC may not be working.

I was on GMsII with header no cat, and aux heat exchanger got a dyno put down 226whp. i had also noticed my trap speed at the track had drop to into the 97-98 range. pump has been fixed ,i haven't re-dynoed but my trap speed is back up to 100-103.

 

problem was already stated
