Default Ported Plenum/Runners

Cusinartvette finished up my plenum and is now working on my TPIS runners. Can't wait to get them installed. Hopefully their will be a noticable incrase. He siamesed it all and gasket matched it. My old runners sucked *** in the clean department. Very dirty. I need to get a new hose that connects to the thorttle body then valve cover. I suppose it's leaking oil somehow?

I got a tune from pcmforless for my new injectors. I need to find a TPIS/Eddlebrock base but they are 300 to 400 dollars so they are pretty expensive.

True duals
Flowmasters
Custom tune
24 lb injectors
Full tune up(better than stock parts)
Ported to the max plenum
ported TPIS runners
Afterarket CAI
Power coupler
Descreened MAF
No Cats
Eliminated A.I.R. pump and hosing
Eliminated EGR/Taken out of tune
93 octane only(personal preference. Not much price difference)

I think the car should be pretty quick compared to stock once it's all put back together.

Any other cheap/free mods I missed?

Cam/Heads Base will be later...

Whatcha think guys? What should this TPI be making torque wise.

86 vette. 330 lbs stock. Hopefully 400 lbs of torque? I don't care about hp as I dont drag/autocross or anything.

Let me add, the stock runners vs TPIS runners are a pretty big difference unported.

Ron does beautiful & very nice cylinder head & intake porting work from his work I have seen here on C4 in the past.

He has the eyes, skilled hands, alot of patience, & much experience at it.

What do they charge for plenum and runner porting?
