Wow, Someone else like the OE Pony too.
I was wondering the same thing. I ported my upper and am using the Steeda spacer and a FRPP 70mm TB. I really couldn't tell a difference between this combo and the Accufab my friend put on his 99 GT.
I bought a C&L but I couldn't make myself replace the pony. Nor could I give Accufab free advertisment on my engine.
Modualar depot got 3hp out of p/p alone, and I know for a 100% on a dyno that a Steeda spacer adds 2-3hp.
