not decided on who's mapping it yet, any suggestions are welcome, central Scotland area. was going to give VES sport a call as they are close by and done a good gob on my friends RS focus. most importantly I went for the free T. lol.
In the 5 years I have been on here I have not heard of anyone company in Scotland mapping these cars, Few individual people have mapped there car but most have had it mapped down south including my car Mickeys car Stevie`s car Bob`s car.

is there anyone you would recommend? and where about down south?mailer555 said:

EFI live if you feel up for it, just because you can fix niggles and tailor the response (degree of engine braking, pops and bangs, idle character, etc.). It is a lot of work fiddling and learning though, so would completely understand getting someone else to do it...but all the info is out there, much of it in guide form.

the people who are generally known to map these cars are,
Wortec
Monkfish Performance
LSV8Power
Greg at ProTuner
You missed Walkinshaw...?Wortec
Monkfish Performance
LSV8Power
Greg at ProTuner
and the people generally advised to stay away from are LSV8 Power!
Apologies i forgot about Walkinshaw, but the other alternative is that you can happily have it remote tuned from the states or Aus, from people like Oztrack, PatG, PowerTorque

AAS (Newcastle) were setting up at one stage to be able to map these cars, but they may have canned the idea. It might be worth talking to them.
Think there still into it but not sure how far down the line they are with it, but I would of just gave them the car the specs you want and let them work there magic. Hold on that's exactly what I did, then the car was taken to someone else for the mapping. are they really that difficult to tune? would a well recommended tuner closer to home not be able to get the same results? and what's the script with EFI live? is that not a really expensive rout, probably don't trust myself enough to try this as I have no experience of it, but would be cool to have a shot. sorry guy's, just got no experience of mapping these cars.

When I did my cam I could not order pushrods till the job was started as they needed to measure them and get the push rods that matched the cam to keep the length correct. That what I was told at the time install.
the push rods and springs came with the cam as a kit, so I think they would be to match the cam?mailer555 said:

Assuming you are using matched parts in a kit and you are using standard GM parts i.e. lifter, rockers, head castings etc.Then there shouldn't really be any reason the supplied rods wouldn't work. You can usually go one size either way and still be within tolerances I've seen stated on the net
For example I was fine with an off the shelf cam kit in my LS1 with Comp Cams 7.4 rods until I ported and skimmed a set of 243 heads. I fitted them and used a CC rod checker and I'm now borderline between 7.375/7.4 rods due to the head skimming mainly and hand lapping the valves. Some are 7.375 and some are still 7.4
GM rockers are fine for most installations or until you start going over .600 lift. They are a very robust design and all have the same bearing design from LS1 to LS7. I have installed a CC trunnion upgrade in mine which took about an hour with a hydraulic press.
Change the GM lifters if you find you have some particularly noisy ones after you fit the cam kit. The tolerances on the GM rockers are bit looser than decent aftermarket ones and I believe the odd one doesn't keep up if you swap valvetran bits. Otherwise they are perfectly OK in your application especially if you have the later LS7 style ones fitted.
All IMHO of course

Tuning for dyno run is so easy anyone could do it with about 30min training.On the other hand idle transition will take 95% of the time and be responsible for 99% of the success of the tune.
Part throttle will take 4% and dyno tune 1% of the time.
Ive helped some guys get started, but the 95% takes months and really you need temps in winter of -10*C and summer of 30*C to get full "cold" start dialled in and low speed low throttle things sorted. Gareth is understanding this fact with his ongoing sampling of global mail order tunes!

It was 'interesting' when the really hot weather kicked in and compromised my cold weather tune...Being self-sufficient is a boon if you like to keep fiddling and adding on bits. It can make it a bit too easy to keep upgrading though!
IMO a local tuner with a dyno is essential if you want something optimal.
Add plenty of time to get cold starts sorted etc and you are heading in the right direction.
This doesnt leave many options. Some local guys dont actually do the tune and dont have dyno's.
Id use that as my filter.
