Hey SGOS, i had the opportunity to meet both Justin from JNJ today, and Jeremy from fastproms. As it turned out, justin still did not have the update to the new specs on the tcm module, and neither did Jeremy. Hopefully JNJ will have the update soon. In my depression, I ordered my 1 7/8 american racing LT headers today, and JNJ is 3 weeks out to install. Jeremy also is offering a ported intake and throttle body for 400.00, but did not have one with him. He says 18rwhp gain. I'll get that car running yet. Take care, Dave
Yeah, I went to Aftermath Performance just off Hanson. They're a pretty good group of guys.
Jeremy Formato (fasterproms.net) goes there a few weeks and does tunes.
They're also a shop out near your (J & J Performance). You might want to check them out. They put headers on my GTO. I believe they also have a dyno. Jeremy Formato also goes by there every once in a while for tuning (not as often as Aftermath though).
Let me know what you do.
Aftermath also put my headers and catback on my Camaro for me.
