There is no time for the gym, only time to post videos! I can't wait to see and hear this beast run.

Here's the 4.8psi graph



I just noticed the dotted line is the stated numbers, hp looks about 10-15 higher, closer to 440ish and tq is up near 400

That thing sounds pretty nasty! No blow off? Or are you on bypass? That's good power for 4.8psi

First, I want to give a HUGE thanks to Shawn for his fabrication skills and S&R Performance for helping us with the tuning and diagnosing the initial problem. Shawn and the guys at S&R stayed until around 9pm when the car was finally taken off the dyno. They all went above and beyond what's expected of them. I also want to thank Jayson (jnaut), Raul (RCZ), and Sam @ GTM for answering my questions and throwing ideas off of them.

What a friggin day! Got the car on the dyno around 5pm at S&R Performance. After the very first pull, the car maxed out the driver's side MAF sensor and goes into limp mode. The code pulled said the the driver's side throttle body crapped out. We brainstormed for probably almost an hour and a half. After blocking off the passenger side throttle body and hooking up an intake from a Stillen SC kit (one pipe with both MAF sensors into one throttle body) that was laying around the shop onto the "faulty" throttle body, the car idled fine and we realized the throttle body was fine. So we put everything back together and the car was fine?! No codes, no nothing. Weird!

Onto the tuning, as you can see on the graph posted, on roughly 4.7PSI that car made some good power! I could finally smile...knowing that this was almost all worth it. A few tweaks later, we did a pull on 11psi and the driver's side MAF sensor maxed out again and the tune leaned out bad....plus the car made less power (411whp) on a higher boost. The passenger side MAF sensor still had about 30% to work with, so we do know that the driver's side piping flows alot faster and is causing the problem. We can either troubleshoot and reweld the intake piping to move the MAF sensor mounts around or I can just order upgraded MAF sensors knowing this will solve the problem. Upgraded MAF sensors ordered!

After ZDays, I'll probably upgrad the injectors to RC750s and possibly change the exhaust housing (.82AR) for something bigger and then do a retune and make some big numbers....but I think for my power goal of 530-550whp, this turbo should be fine.

You figure the TB issue is related to using different intake tract lengths?
