Dyno/Tune experts, please step in.. had my car dynoed over the week.. the car seems to fall everytime it reaches ~5300 RPMS all 3 pulls for just a bit. same time, same drop same RPM.. mainly in 4th gear.. on the highway, if i stand on it in 4th, when i reaches ~5300 RPMS, it feels like i took my foot off the gas..bogs pretty bad...but 1st, 2nd, 3rd pull to 6000 RPMS with no problem. no check engine lights. car runs 26 spark.. and about 2.7 knock retard at that RPM..
it's a 2000 FRC w/ 30K miles
mods:
-halltech stinger
-Z06 intake maifold
-Z06 ti's
-Kooks 1 3/4" w/ 3x3 cats
- NGK TR55 gapped @ .045 w/ Z06 wires
the car has NO tune as of now. is this more of a tuning problem, or should i start looking at somewhere else? valve float? other than that problem, the car runs fine.
thanks in advance,
vinnie

it was suggested by the place i had my car dynoed.. they thought it was a spark issue...it was at .055. now i re-gapped them to be .045 as suggested by a tuner.
