Here is another lesson in what not to do...
We took apart a car that was built by another shop and found this crazy hacked together blow-through MAF setup:
This is exactly how you should NOT set up a blow-through setup. You have to keep the transitions as smooth as possible. Instead, this shop decided to just stick a smaller pipe into a larger one and weld it. This creates tons of turbulence, throws off the MAF sensor, and makes the car very inconsistent and very difficult to tune.

Here is yet another build we did recently that finished his break-in and came in for the final tune today. This is a 2010 STI with EQ Stage 2 block, Stage 2 heads, ATP GTX3076 turbo with EWG, upgraded TMIC, EQ 1000cc injectors, UEL Headers, TBE, AMR Intake and supporting mods. This tune is at 20psi on 91 Octane:
On the street the car hits full boost at 3800RPM in 3rd gear. It feels great and pulls hard all the way to redline. Next up some race gas or E85 so we can wake this turbo up

^ On the way home we did a few pulls in tunnels. Was a bunch of LOL's and fun with that EWG, Paul's loving his car Ed. I can't wait to get all my parts now and go E85.
. Haven't had a significant power gain in 2 years. Have to make 400whp!!

We just had a sexy red 2011 STI dropped off for stage 2 engine build along with AMR rotated big turbo kit, FMIC, etc, etc. This thing should be a beast when its all set!

Here is a tune I did earlier today. This customer came in about 6 months ago with a built engine from another shop. He just wanted to get a custom tune on E85. After the first pull on the dyno, it was clear that he had a blown/leaking head gasket. The car was literally dumping out coolant from the exhaust. The customer saved some funds and brought the car back in for a head gasket replacement and some head work. He put some miles on it and brought it back in today for the final tune. Here are the results:
This is an 05 STI with a 9:1 compression engine, Element GT52 turbo, APS FMIC, APS 70mm CAI, DW1100cc injectors, Headers, TBE, and various supporting mods. The injectors ended up maxing out at only 21psi. Therefore, this tune was done at 20psi to keep things safe. The nice thing with the higher compression is that even at 20psi, the car made some great power overall. It did seem a bit too laggy for the setup, so the customer will be checking for cracks in the header or possibly warped flanges. Even with this lag, however, the car feels great on the street and really gets going well especially for only 20psi!

The only real difference is that with Speed Density, the ECU is not using the MAF sensor for its fueling and load calculations. Instead it uses the MAP sensor and a VE table and performs additional calculations to determine how much air is going into the engine and how much fuel to inject. This is mainly useful on large setups where you are maxing out the MAF sensor range or on FMIC cars where the MAF location is not ideal.

Did a compression and leakdown test on an 02 WRX that drove down from Roseville today... 70% leakage on #2 cylinder. The interesting part is that compression looked really good all around. Leakage was found to be coming out of the exhaust so its likely a burnt valve or possibly a severely cracked head. Its pretty amazing that these motors still run like this!
