My "secret sauce" will be done soon but I'll share.

OEM TB- 2.6" to 2.35" to 2.39".
New TB- 2.6" to 2.55" all the way through.

OEM mani ported to 2.55" at the TB connection and smoothed out runners port matched to the lower mani. Lower mani port and polished as much as possible.

Lowest base I have is 280hp 226tq on a dynojet SAE with rpf1 18" wheels with light weight tires (like 12lbs off OEM), custom cai with OEM accordion post MAF tubes, and topspeed pro 1 true dual CBE with added 18" vibrant resonators.

Then 295hp 243tq same dyno SAE with added Z1 MAF post tubes, muffler delete, Helmholtz resonators added to the X pipe, and ebay LTH wrapped.

Soon will be port and polished TB's and mani's with a tune.

Then maybe later e85, ID 1000's and a walbro 255 with retune.

I'll always do SAE but maybe I'll do a STD to show a difference from our DJ to Z1 and TSM since their two read so much higher than everyone else. If I can't reach 230hp, Z1 and TSM are aiding the dyno numbers. Since both dyno's have had the same tuner involved working on them, I smell something fishy unless I can show similar results.
