pulling timing-how much power loss?
I have a wet/dry combo set up I am working on and I was needing some insight on something.....I have the dry kit set to trigger the MAF to retard timing when juiced. I am going to run a combo of 150 total with 50 dry, 100 wet (TNT F1) and was thinking about 2 staging this set up to help traction.
My tuner has my tune set so when the MAF senses the nitrous it will retard my timing from 28* n/a to 18* on nitrous. I know alot of people dont take that much timing out but he did and I know its a safe tune.
My question is that if I seperate the wet/dry combo so that the dry comes on alone and later the wet kicks in will i see any more power than n/a with the dry kit alone since it will be pulling 10* of timing out of the car? Or will that just make up the loss of the additional timing?
Thanks in advance.

Heck, I've heard of guys going to the other extreme and spraying 125 shots on the stock 28 degree tune, I wouldnt try it though.

I've run 150 on stock and + timing, but I prefer to tune the car more on the safe side now. So I have the timing lowered to 22* max NA airflow timing, and 15* for the big shots from NA to max period airflow. 10* for a 100 shot it killing the power.

What exactly does pulling timing do when running nitrous? what do I need to look for so I can keep it safe and still get the best/safest power from my set up? Mainly need to watch Knock or what? So pulling 6* is more than likely a safe starting place and not the 10*?

Thanks.....I need to borrow my buddies HP Tuners and figure out how to scan live data and check for KR and timing......Also need to figure out how to change it so when my MAF reads the nitrous it only retards 6* other than 10*. Any quick tips to do these 2 things? Im not real familiar with HPT but dont mind learning.

Wow thats alot of timing pulled for your set-up.
For me i have had NO issues with a 150 wet (RWHP) and the timing i got from my Predator hand held programmer(30.6 deg). i have sprayed this car for 3 years and more than 60,000 miles.
No spark knock ever for me.
Good luck,find what works for you with all the advise you are finding.
Mine is not advise,just sharing info.

While dabbling with my install, and monitoring with a Predator, I saw 6° of KR on I think a 125-150 pull and we pulled max timing on the Predator for the next run(I think its 4° but it is shown as 10%). We pulled timing and saw 0 on the next pull same jets. We upped to I think a 175 shot and saw 2°KR. We stopped there as we run outta time.
June 11th we are going to redyno and try tuning the dry with different nozzles. I will make a better effort to record the settings and timing/KR for each jetting. I am hoping to settle out at 450 at the wheels with a combined 150 shot Dry/Wet.
I am running a RWTD N/A tune, and modifying it for N20 on the timing side.
