RXP: Would ya?

[Who Needs 8]

So I went to take my truck inspected and it failed emissions. First time in 190,000+ miles ain't bad. But anyway, I'm going through all the stuff to make it legal and I decided to put some RXP in. I already can tell the difference in performance, which is still slow for a 15 year old almost 200,000 mile stock block truck. It has alot more pep.

I've got half the bottle left of RXP. I'm wondering if it would help clean a few internals in the TTA. Anyone know if it'd hurt or benefit?
