Where is my power?

[section525]

191.53HP 217.36TQ

This is from my '96 Explorer 5.0L

K&N Intake
E-303 Cam
1.6 FMS Roller Rockers
FMS Headers
Explorer Upper
GT40 Lower
GT40-P Heads
Apten Chip
70mm MAF
65mm TB
19# Injectors
AOD-E
Stock Exhaust (with all 4 Cats)


A stock Explorer (with intake and exhaust) dynoed at 157HP and 221TQ. Where the heck did my torque go? And shouldn't I be making more HP? Thanks!

im probably TOTALLY WRONG, but i think ur exhaust is the problem

doesn't flow enough, especially with all 4 cats, some of them might be real clogged or something

IM PROBABLY WRONG but thats my guess

Yeah. Thing is I only have about 12k on the system.

o ok.. my fault... maybe also ur injectors are to small? im not sure, im trying to lend a helping hand to maybe allow u to figure it out.. i know that alot of people have problems with power when they put alot of mods on, becuase the engine isn't getting enough gas and is leaning out.. i dno... someone post and yell at me for being wrong
