Thread: Something Positive , perhaps to do with recent head work?

It seems I have so much more down Low and Midrange Torque , and it feel more flatter to say the least , so would the fact that there's been recent head work done would have something to do with this ? the power was never that smooth and crisp she pulls away quite nicely with 285/75/16.

I have driven yours so can say it does well for a 3.9 with 3.54 diffs and the tyres you have.
I recon it would out run the stock 3.9 90 model I have here with 205/16s.
It is not near as responsive as yours in the mid range revs.
You still got that dead lock up in yours?

the weird thing was that the whole time I was driving it , it was done on Gas , seems to be tuned well for LPG , when I switch over to Petrol ( E10 ) the engine seems even quiter and power is still even more smooth.

would it be any advantage to run a tank of Premium unleaded over say every 2-3 tanks of E10 ?

Your running a dual advance module right. So should be tuned to run the crap unleaded with out pinging wile under load and still get the advance needed for LPG

I doubt running higher octane will make any difference with the given compression ratio It has. Stick that blower you have on it may be a different story though
