Just curious... Recently I installed a F&B 50mm TB and replaced the stock
PCM with a Mopar PCM (CA Emissions, Federal.. which I'm not in CA, so I
don't have to have the CA PCM)... And although the HP output on mid-high
RPM is awesome, seems to me that I lost some/lot of low-end Torque.. for
example, I could baby it to about 5-10mph, then go WOT, and would spin the
tires (dry) for probably 15 feet before they'd stick.. after the recent TB
and PCM installtion (did 'em about 1 week apart), it's hard to spin the
tires at all, unless I go WOT from standstill or road is wet.. Once I hit
2-2.5k rpm, takes off like a rocket, but it's a little slow before that...
I thought it may have been due to the hot weather, but it's been in the
mid-upper 70's here this week, and still isn't taking off the line very
fast.. not really even at WOT.. Starting to wonder if it's the Mopar PCM
(which I'm piggy-backing Hypertech PCM on).. when I took the Hypertech off,
I noticed lost HP, so I put it back on (even after resetting the computer)..
Also noticed it doesn't ping/sparkknock anywhere near it use to while
towing.. really starting to make me wonder about the mopar CA PCM..
Thoughts???? Maybe time to invest money in some headers??? =D
