So I did my first Dragy run with decent air temps. This is on the street. I know the 60' sucks but I thought I would be a little faster than this. My mods are stage 1 tune and the AD Trans Mount. 1/4 tank of gas and good fuel. The reason I mention a boost leak is because I sent a data log to Ortiz last summer and they thought I had one. This might be conformation of that. Still faster than my 98' GT back in the day lol. Still fun. Need to get hot pipes, intercooler and fuel pump. Just love this sh*t :)

Look at the slope on your graph, it obvisously started the timer early. Probably bumped the car and didn't let it sit still long enough for it to reset.

That being said, Ortiz is notorious for telling people they have boost leaks when they obviously don't. Do a data log of a 1/4 mile run and look at your wastegate duty cycle percentage. If it stays pegged at 100% you have a boost leak. If it doesn't, you can save yourself the time wasted looking for something that doesn't exist and wasting money replacing things that don't need replaced.

Funny you say that because I did try and bring the boost up and I think I did move a tiny bit. I will give it another shot and data log as well. Thanks for your help!

Whenever in doubt, pull up the 0-60 graph for the same run, it will be even more apparent in that graph. Probably only a tenth or two difference, but for comparison's sake between two runs that's a pretty big difference.

Just want to get into the 13's. Brought up my data log from last summer and the BOV was at 100% but I will do another one tomorrow to see what's up. Still having fun, love driving these cars ******* the WI backroads and interstates (such a cruiser) so if I can fix what needs to be fixed I am good.

Should do 13's stock, you should be able to get into 12's on a good air day with a tune.

Did the drop of soap in a sprayer and I didn't see any bubbles on anything up top when running. Will probably pull the BOV's today to check them out. Should just bite the bullet and get new hot pipes. I think you said that if you did it over again you would stick with the stock ones.

100% would go with stock. Price of aftermarkets are insane.
