I installed the polished Accufab throttle body and inlet today. The install was very simple, except I stripped one of the screws that hold the TPS, so I had to go and buy another TPS because I didnt feel like screwing with it I know, I am lazy. Got the TB on and I had the high idle, adjusted the screw a bit and now it idles like stock. My SOTP meter did not really feel much of a difference, even on the top end, but I was ready for that. The pedal is a wee bit sensitive it feels like it goes to WOT when the pedal is moved about inch. Kinda weird at first and had to feel it out but I can see how this will be good at the strip. Sorry to ramble on.....I do have a few questions now.
1) Concerning "tip in" air / fuel , I am wondering if an updated tune from HBH with a few tweaks could give me the 10 or 15 HP that can be had with the T/B and tune adjustments?
Obviously, this thing flows more air, so I would think that my A/F would be leaner, but some say that, since I now have a lean tip in, the EEC5 will compensate by dumping a bunch of fuel in there, and all the potential power gains of the increased airflow are lost due to the added fuel. Is this true?? Or is my car leaned simply because of increased airflow. I do have a tune from HBH, would the EEC still dump fuel in there, even with a custom tune??
Would there be benefits of an updated tune, (this is the only change since my car was tuned), or should I just sit on this tune for a bit? Any thoughts?? Thanks
