This car belongs to Jonathan of Rock Hill, SC. He brought his setup to us for an E85 tune on Crome Gold and boost by gear install.

Here is Jonathan's setup:

Cast Manifold
50 Trim Turbo
2 1/2" open downpipe
Electronic Boost Control Solenoid
Turbo XS BOV
Turbo XS Wastegate 38mm

Walbro 255lph
880cc injectors
B&M Adjustable FPR
E85 (base fuel pressure @ 52psi)
GM 3 Bar MAP Sensor

B18C
9:1 Mahle Pistons
Eagle Rods
Toda Springs & Retainers
ITR Cams
Edelbrock Victor X Manifold


The wastegate wouldn't hold boost steady. AT around 6.2K RPM's it hit 18psi and tapered down to 14psi by the time it hit redline with some fluctuation along the way, hence the power/torque waves. This was on 3rd gear like the majority of other setups. For those wondering, 4th gear yields a/f rations that are roughly .5-.7 richer.
