I've tuned quite a few different makes with different airflow setups and EMS systems over the past decade. I can't say that I haven't been able to get driveability of a MAF setup with a MAP. MAP has always been easy to tune on, maybe easier than MAF; that really depends on the EMS software...

Is the check engine light on? What reason did you change the tps?

I just use any old air die grinder. I've used just about every mid-range die grinder, not a whole lot of difference. Right now I'm using a husky but the trigger lock slides against plastic, so it's not as smooth of an action. Look for something with a trigger lock that slides against metal for a...

Exactly. Remember; if you ever want more power, it's easier to change your tune than change your pistons. Go with the slightly higher compression pistons if you have the ability to get it retuned.

I ran a similar setup for (9:1 Wiseco's, bastard 20g) for a couple of years on pump for a couple of years without a problem. I've recently tuned a couple of 9:1 pump engines; one with a ebay 20g on 22psi, one with a GT35 at 20psi. They usually require a little less timing.

For grounds, just make sure you have a good metal to metal contact from the transmission to frame, intake manifold to frame, battery to frame. You can't have these bolted to a painted surface; the bolt alone may not provide sufficient ground area.Also, make sure the heavier gauge wire(s)...

Did you install a OEM plug and play fan or an aftermarket? I can't remember the exact temp. the fan will turn on at, but if you reach 210* and it hasn't, you have an issue somewhere. Check your fuse and relay; check for continuity from the fan wiring to the oppoiste side of the relay. Do you...

You need to fix that wiring, then let it idle and check charging output at the battery with a multimeter. I've spent days diagnosing poor charging system output that turned out to be a bad wiring connection or blown alt. fuse.

Yes, you will be ok with those injectors with ecuflash; I've run twice that with very little affect on driveability. You'll want to get a wideband or have it tuned asap, but you shouldn't have any issues with just scaling the injectors.

Nothing you can do once the rings have been washed out. It usually ruins the rings and scratches up the cylinder. You'll need to tear it down, replace the rings and rehone the cylinder and hope nothing else was damaged.It's a little strange that the issue showed up immediately after the cam...

Just got around to inspecting the cams I pulled a couple of weeks ago from my 7 bolt. The previous owner claimed they were 272's, but they looked stock to me. I noticed a few numbers stamped on the end of the intake cam though, wondering if anyone could ID these for me or if those numbers are of...

What did you use for a throttle body gasket? I've seen rtv clog vacuum ports. Pull your tb off and check the IM side for obstructions.

Board traces can be pulled up at the eprom/socket side too, and can be difficult to notice without pulling the socket out or checking continuity. If you continue having problems with that ecu, I'd either send it in to the guys at ECMlink for repair, or cut your losses with it, buy another pcm...

What wideband are you using to tune with?
