Some updates on my new 78mm BBK Throttle Intake and dyno situation

So my car was dynoed today... Here are the numbers from several runs. The car was running extremely lean at WOT, so the initial numbers were low.

Baseline: 238whp/242tq
After making some tweaks with my Xcal 3 to fix the AFR: 245whp/282tq
After installing the BBK Throttle Intake: 242whp/279tq

Now, the car is still running a bit lean, which is why I lost 3whp/3tq with the 78mm TB on, untuned. Feeding more air into the motor isn't helping the AFR, obviously. The car will be getting a complete dyno tune on Monday with the new BBK part on, so I'm hoping after that I'll gain a bit since as of now all the tuning was done off of my handheld.

Final note: The guy who claimed to pick up 10rwhp off of the BBK 78mm Throttle Intake (without a tune, mind you) must have been a little full of it. Like I said, I lost 3whp/3tq by simply installing the piece without a proper tune for it.

That aside, I'll keep you guys updated with numbers after the full dyno tune is performed on the car. I'm glad that I at least picked up almost 40ft-lbs out of it, though. I can't believe it was that low! Plus, I got my Terminator bumper on last night, I'll have pics soon!

I'd love to get a tune for 93, but here in northern CA, it's damn near impossible to find gas stations that sell it.

that was me, it was my brothers car. Im getting ready to install a ton of stuff on my car, I have easy access to a dyno, so Im going to take off my tb and plenum and see if I lose power. Also have a BBK 78mm to install so I can do that this weekend if needed. I can take pics, videos, dyno sheets what ever you guys want.

I'd appreciate that, thanks. Like I said, this isn't finished yet as a full dyno tune is complete to come.

BTW - I have a C&L 80mm intake and MAF.
