Here's the build sheet

S2000 build- with full exhaust it made 385whp with open DP it made 418whp. 16psi about 14* timing, any more and it picked up knock. Power seems a bit low. Any advise?

What exhaust system are you running?

 

Open Downpipe so no exhaust

The 385whp with full exhaust is 3" to the stock mufflers and resonator. No cat. Then we disconnected it and ran open downpipe and it made 418 so the exhaust is a bit restrictive but we still couldn't add anymore boost or timing without picking up knock up top.

 

Who's tuning it? Im in the DFW area as well.

 

What fuel are you using?

 

I second Jin and Liquid's questions, and is the tuner familiar with aem?

 

Boost and timing is only a fraction of tuning. Like the others, what fuel are you using? What does ur fuel trim tables look like and afr?

 

I'll post the tables In a bit. 93 oct

 

He's got one of the best in the business tuning it. He doesn't specialize in S2ks but he's done plenty of big power and 'on the edge' tunes to know his way around them. That dip in torque looks like something isn't right, maybe check for leaks around the couplers / wastegate.

Is boost staying steady / not falling up top? Fueling *should* be adequate with a 340 and ID1ks
