XLR8NSS, are you still using the VVT and the VVT timing table? That could cause some knock issue's at part throttle for you. Just a thought.

i run a EGT, boost, and wide band gauges

my just changed to a bigger turbo and 80e from a 65e but had the t70 in there and dynoed 550 hp with the t70 and everything else in my sig is about the same as yours on 9 psi...

Not sure if this is useful or not but have been towing a 6500 lb travel trailer during the summers with my Maggied Denali for 4 years now (longest trip approx 500 miles in 100 degree heat). Max boost I achieve is 5 lbs (3.1 inch pulley). EGT at times up to 1600 when cranking it up a hill but most of time in 1200 to 1400 range cruising at 60mph or so.

So I think if keep boost under 6 as recommended when towing should be good to go.

Good luck. By the way, what are you 0-60 and 1/4 mile times with that turbo setup?

p.s. also have a 2 bar tune.

I have been running 10psi on my LQ4 for about three days now.LOL So far I am at 16.5 degrees of timing and no knock but I am spraying 2 625cc meth nozzles. I did a 8psi launch tonight and had the truck sideways in 4wd. Hopefully I will get it to the track soon. Good luck with your tune.

VVT timing tables are zeroed out completely for now. The "island" in the table for cruising causes problems with the bypass valve operation because of high MAP. I might try retarding the cam some as rpm rises like the stock table does now that my tune is dialed in pretty good.
