Should I go bigger? TB, Injectors, & 3" exhaust?

[STREETFIGHTER50]

The car made 410RWHP/410RWTQ recently on a Dynojet. The combo is a 10.7:1 compression 347 w/C&L 76mm MAF & elbow, 70mm TB & EGR plate, FMS 30lb injectors, RPM II intake, custom cam w/244/236 duration & .580/.555 lift, 1.6 Pro Magnum RR's, AFR 185's w/polished exhaust ports, BBK 1 3/4" LT's, Dr. Gas 2.5" X, & 2.5" Spintechs dumped.


I have these parts sittin in my garage:

80mm C&L MAF
Vossperformance Race Induction 3.5 pipe http://www.vossperformance.com/pictures001005.jpg
FMS 36lb injectors
Accufab 75mm TB
UPR 75mm EGR delete plate
RPM II-port matched for the 75mm TB & tapered in
BBK 1 3/4" LT's opened up for a 3" collector
Dr. Gas 3" X


My Q's are:

Are these 30lb injectors & 2.5" exhaust maxed out @ the 410HP?
Can I install any of these parts listed above without hurting the current tune on the car?
Should I skip the 36lb injectors & go straight to 42's?

Those sound like excellent upgrades!

Absolutly do the 75mm tb, bigger exhaust and bigger injectors. Your tune will be off if you have a custom chip in the car.

My 30's are near maxxed out up top (6500+ range). I need to step up to a 3" exhaust badly!!

I would think that the shop that performed the tune would know if the injectors were maxed out or not.

They may even still have records of your dyno time?

I would give them a call and see if they call tell you what your AFR was in the upper rpms.

Or, you could just install the parts and have it tuned again.
There would be a power gain.

I may just add the Vossperformance CAI, 75mm TB, 75mm delete plate, & matched RPM II upper for now. Think I'll gain a little more & not hurt the current tune as I probably would changing out the mass air & injectors. Just for now at least. What yall think?
