How do you select a good engine tuner

[ROZ]

Hi all,

What questions can I put to a tuning shop in order to know which one will be right to tune a FFS h/s installation? They could tell me in greek, and I might pick up as much!! I probably know more than I think from reading through the forum, but if you guys could spell it out I'd really approeciate it.

:cheers2:

If you are tuning and don't care what the WHP numbers come out to be, any dyno will do. All you are looking for is to be able to draw a HP and torque curve and an A/F curve vs. RPM. The HP curve should be relatively straight and increasing from start to redline. The torque curve should be relatively flat across the RPM band and the A/F curve should be relatively flat and around 1:1 above 4000 RPM. Below that, the A/F can be as high as 13:1 with no problem.

If you want to know the real numbers, then you need a DynoJet dyno as that is what the numbers are based on.

They all work basically the same, only the WHP/Tq numbers change from dyno brand to dyno brand.

Missed a key stroke here Tom or am I way off. Looks a tad rich to me! Not to worry as I have missed a shift or two myself !

Not trying to make excuses but it could be the almost 6000 mile I have driven in the last 2.5 weeks or typing on the PDA. But I won't make excuses. ;)

Yep, that 1:1 should be 12:1 but what's a 2 among friends? :)

SO find out what dyno gear they have and report back?

That is a good place to srart. DynoJet is preferred.
