Once again a run down of the performance mods:
- Engine - Engine was bored 0.030 over, Manley H-beams, DSS blower pistons with 8.5-1 compression.
- Vortech S-Trim Supercharger
- 42lbs. injectors with a lightning 90mm Mass air meter
- Walboro 255 fuel pump with T-rex pump
- Flowmaster mufflers
- Bassani X-pipe
- FRPP shroty ceramic coated headers
Problem:
Around 4000 it starts to stutter and hesistate....and falls on its face.
It's only boosting 5 psi now and I have no clue why....
I had a FMIC on it and was having boosting problems so I completely took it off.... and now running like the kit came with.. and USE to boost 10 psi...
Now and with the FMIC it falls on its face at 4000-5000 rpms and won't boost over 5 psi or so.
I have no clue why and it's really really bothering me.
It also has ACCEL wires and pack... do those suck? Could they be the reason?
Could the stock vortech bosche by pass valve crap out on me?
Could it be spark plugs? I have pretty damn new NGK TR6s in it... (less than 2k miles)
Any help please?
Its really pissing me off.. we went out running tonight and I lost to EVERYONE..... (a few pullied terminators , turbo swap wrx)
I'd out launch the hell out of everyone big time with my et streets but after that it fell on its face and I'd lose the race... pisses me off... :slap:
