-Make sure your engine is in good shape. Compression numbers should be within 10-15 psi variance between cylinders and leakdown test should show under 10% leakdown between cylinders.
-Please triple check your cam timing to make sure it is synced with the crank at top dead center before coming.
-Fix any cooling issues before coming. Do not bring us a car that overheats. Also do not bring us a car that will not get to warm-up temps.
-Do not use rubber charge pipe couplers like what you can buy at Lowes or Home Depot. They will rip and give us boost leak problems while tuning. Use good quality silicone couplers with T-bolt clamps if you plan to run a decent amount of boost.
-Make sure you have an O2 bung in your exhaust before the cat. It must have the welds on the inside of the bung completely grinded down or my wideband O2 sensor will not fit all the way in as it is fatter at the bottom than a stock narrowband sensor.
-Also ensure that if you are open downpipe that the sensor is at least a foot from the end. The open air will throw off the sensor's readings and I will not be able to give you an accurate tune.
-If there are any exhaust leaks anywhere near or before the o2 bung then make sure those are fixed.
-Make sure you have a dumptube with sufficient length so its not blowing hot exhaust gases into your turbo's compressor inlet. This will often cause great power loss.
-Do not bring us the car if it is throwing CEL's. If you have a question on why it is throwing a particular code then it can be diagnosed (additional fee required) to solve the issue.
-You must also have a lower timing cover on the car so we will be able to properly set your base ignition timing.
-If your injectors are low impedance (AKA peak and hold) then make sure you have an injector resistor box wired into your harness.
-Do not have wires simply twisted together. Make sure every wiring connection has been soldered.
-Make sure you have good clean grounds.
-Do not have any fuel leaks
-Do not come to us with excessive oil leaks
-Check to make sure the turbo is in good shape. Don't bring us a car that is blowing constant smoke out of the tailpipe because the turbo is shot. Ways to prevent this are by not running an oil feed line any bigger than a -3AN, and ensuring your return line is routed to ensure proper oil flow. The return line works off of gravity and having a huge dip in the line will cause oil problems for sure.
-Make sure all of your ignition components are in good shape and reasonably new. OEM components are recommended. Please do not use cheapo Autozone/Advanced Auto/Pep Boys type wires. OEM wires and NGK's work great.
* Bring at least 2 sets of spark plugs to the tuning session.
-If you don't know exactly which plugs will suit your application then contact us and we will help you make a decision on it.
