carazy Member 27 Member For: 17y 8m 15d Posted 30/11/07 10:31 PM Share Posted 30/11/07 10:31 PM Hey guys,Just put the generic tunes put on my stock XR6t Mark II BA. 8psi runs perfectly, so does 10psi actually. It's smooth and crap loads faster. I put it on the 8psi tune 2 days ago and the 10 psi tune last night. Can't hear any pinging and it really does run perfectly. Should I still gap the plugs down to 0.8mm? I don't know what they are at the moment but if it's running so well do I need to change anything.

Might get it chucked on the dyno to check A/F ratio's otherwise.. I'll just leave it. More then happy with the power though. Now I just need to spend some money on suspension Link to comment Share on other sites More sharing options...

The end result is bent rod/s.That happened to me and cost me an engine. Not a pleasant experience. Link to comment Share on other sites More sharing options...

If you run generics without regapping and without sticking it on a dyno, you're taking a stupid risk. Spending a few bucks can potentially save you thousands. When I blew mine, I didn't hear any pinging either. I had the 10 psi in for no more than 45 minutes before it backfired under full throttle and bent 2 rods. If you do break it, expect to spend somewhere around 4k to get it back to stock.Dont forget if you do blow it and have to get a new motor, specify the Tzatziki injected variant as this is superior to the lesser Tabouli injection. The science lies in that Tzatziki lubricates the cylinders about 90% better than Tabouli, causing less friction.

They say the NGK humus core plugs don't need gapping and are virtually "blow out proof".. Link to comment Share on other sites More sharing options...
