When they tune these cars , can they adjust spark timing, like to advance or retard it? It seems like my spark isent strong enough at higher rpms.

Oh yea, they can do MANY things to it. Being OBD II, most dyno places should be able to if you have the money ($500 at least I'd say), and more accurately tune it.

If you haven't tuned it yet with all you have done, then you really should :S But I assume you have.

Some options if it has been tuned: Call a dyno place and find out if they can, then see if they'll not dyno tune it but just pull/add some timing. Do a Mail Order from PCM For Less or MadZ28. Or find someone on here who lives by/close to you in Mich and have them tune in some timing.

I just got my tune from Bryan at PCM for less for my cc306 cam swap. The tune is great and everything is dead on perfect. I highly recomend them.

Did you ever run it before you had the tune done? Did it run weird before? how much does it cost threw pcm 4 less?

PM me any questions. The prices are on their web site. My car idled ok but if I tried to give it any gas at all it blew a ton of black smoke. It also seemed like there was nowhere near enough power for what was done. My tune at the time was my old PCM for less bolt on tune so that's prob why it at least started. I got the new tune and other than me not having my 58mm tb installed yet the car is completely different. I've only driven up the road and back but everything seems perfect. My car also tries to pull the front wheels if I get on it a little on the street.
