if he says 350 he could get lazy with it. if you pay the asking price then you have reason to bitch and bullshit and be anal about it until you get what you want (with supporting mods ofcourse and within reason). the extra 150 is basically a guarantee.

Exactly. I dont understand people who will go to another dyno shop just because their quote is 50 or 100 bucks cheaper and then they also use an inferior machine.

These are also typically the customers who would rather just get a better peak output number than really mind beating other cars in an actual drag race where real road power matters.

Just to put things into perspective for a proper tune in a lot of Dyno Dynamics equipt shops the 5-6 Hour Package is between 150-200 dollars per hour.

But you get EVERY SINGLE CELL in your MAP tuned DEAD ON. No gay roller power pulls and rushing the car off the dyno.

I can build you a timing map and you can tune your fuel map cruedly with a couple freeway or highway pulls up to 100 and use a Wideband 02 sensor to log and then adjust a couple times and you're DONE.

But this is not a serious dyno tune or a detailed technical cell by cell solution for a long term map that is going to be tested in all spots for tractive effort, AFR, tip in throttle and even part throttle torque/hp build up.

You can get a car tuned with a wideband and a one size fits all general timing map for 350-450 bucks but you are going to be missing out on soo much more power and more importantly that violent smooth as silk feeling that all the top shops get out of their house cars with hours and hours and hours of cell by cell tuning.

I say invest at least 500-600 dollars for 4-6 hours of solid tuning. And always ask if the shop knows what steady state tuning is. If they have never heard of it I would be wary, and if they have ask them their opinions and voice your concerns about getting a thorough tune.

Another thing to ask is if they have Baro and altitude correction, i.e. weather station hooked up (all dyno jets especially must have this). Also as if they are going to be able to print you your Power Graphs with "smoothing" turned all the way off.

When smoothing is turned off you will be able to see all the giant dips and valleys in your power curve that is going to be felt in your foot and also make your car more jerky, less consistent, more prone to knock and less reliable over time to maintain the level of tune or peak output you are looking for in your tune.
