hey all. I dont think this should happen, but i think it did. Alright, i have an 01 gt with cai, k/n, 410s, accufab 70 tb, plenum, intake spacer, underdrive pulleys,diablo sport tune, bassani off road x, and bassani racing after cat.
aight, i have the bassani x you can run either catless or catted. i had the cats on for a while, but i wanted to try it without, so i popped them off and reinstalled right? well i swear i lost all of my bottom end. It feels like a damn civic lol. does that make sense? could the plenum or anything else hurt? I noticed it around the time i installed tb,plenum, and catless x.

any suggestions please?

um, if your comparing your stang to a civic then I think something is wrong. I've heard a few people say the same thing about adding an x-pipe in general, but I can't possibly imagine freeing up the airflow is going to drop it that much.. The plenum/tb is where I would start the search.

When i added my x-pipe I felt the exact opposite. I acutally had to adjust my launch technique by a few hundred rpms because I was hoppin more. I'd offer more on the plenum/tb thing but I refuse to buy them and thus have no experiance.

I noticed an improvement with the Plenum/TB combo but did notice a loss of TQ with the X. It was explained to me that there was no loss, it was just spread through the entire RPM range. I still don't quite understand that, but that's what I was told.

yah, i would have to assume something was not installed correctly or something, every dyno i have seen has been either = or better in all rpms for both mods..

lol i of course was exagerating with the civic thing but still. it feels different, and not in a good way. the only thing i can think of would be the tps sensor, what ya think? anything else besides seals ?

so u got an accufab plenum and a spacer on at the same time??? the accufab plenum has a built in spacer, so that might be costing u power, and u lost bottom end torque probably, but u prob gained top end hp, the sotp dyno can lie to u sometimes so u might have a problem or your power curve may have just shifted
