Mountain Elevation Riders
- Intercooler Upgrade, Part # MTV-1100 $1449.00
To control intake temps above 7 lbs of boost I would recommend a intercooler, this also comes with a billet blow off valve, quicker response waste gate, etc.
- Fuel Pump & Regulator Upgrade, Part # HSK-1168 $319.95
In order to run above 8 lbs of boost at 6,000 foot elevation or higher, a fuel pump and regulator upgrade is required, this is for the guys who really want to turn up the boost.
- 4th Injector Kit Upgrade, Part # HSK-1169 $449.00
The stock injectors will run out of fuel around 10-11 lbs of boost when used at higher elevations, this 4th injector kit will allow you to max the turbo out and still supply plenty of fuel.

- Fuel Pump & Regulator Upgrade, Part # HSK-1168 $319.95
In order to run above 6.5 lbs of boost at low elevation, a fuel pump and regulator upgrade is required, this is for the guys who really want to turn up the boost.
- 4th Injector Kit Upgrade, Part # HSK-1169 $449.00
The stock injectors will run out of fuel around 9 lbs of boost when used at low elevation, this 4th injector kit will allow you to max the turbo out (14 lbs) and still supply plenty of fuel.
- Also for you low elevation riders, I have a head shim which will drop your compression ratio from the stock 11:1 compression down to 9.5:1 compression. This will allow you to run 9 lbs boost on 91 octane fuel and if you can continuously get good 93 octane fuel you could run 10 lbs of boost on pump gas. This kit includes a head shim & ARP head studs and is $279.99 for everything.
