Disappointed w blower performance

From disappointment to hope! Meth cures it all!!
I went to the 1/4 last Wednesday and ran a best of 11.06@119!!! To some this would be a great time but for me it's just lame. Sorry but I ran 11.32@123 without the blower. Something was happening that it was nosing down in 3rd gear and it simply felt slow. I had some knock on the street even though my timing is set very conservative and I always run shell 93.
So last night I went to the track again with new one step colder br7efs and skinnies in the front which I never used before even when n/a and althought the it was pulling cleanly to max rpms the track was completely crap!! My best 60ft were 1.80 and missing 3rd I got 11.69@121. The car will simply blow the tires even at 15psi on my MTs.
Attached are the timeslips from Wednesday. Read them from right to left. The DA was around 1000 on Wednesday and around 400 last night. I honestly want to sell the blower. It seems like I have to deal with engine heat soak or high IATs during each run. So the performance at the track will be marginal compared to the street and when n/a. My buddy also ran 10.86@128 Wednesday on his 09 cam only, halltech, full exhaust, 4.10 gears and drag pack. We were very close to each other while n/a and now just beat me!! I really don't want to do meth since it's another system to worry about. I'm just beyond disappointed and feel that I just wasted my money.

Sorry to hear that man. That really sucks. There's something really wrong here.
What kind of blower setup is it, and what else do you have done to the car?
If it's spinning violently (like I am now after a Heartbeat install) then for sure it will most likely ET less, but your trap speed should be significantly higher than before, not lower!
Who did the install and who tuned it? If it was someone other than you, what are they saying? If it's nosing down in 3rd, that sounds like a serious fueling problem. Better check that out. Are you monitoring fuel pressure? Could be your pump is failing.
Something is seriously off here. There's no way that your car shouldn't be trapping at least 130+mph now, no matter what kind of blower/boost you're running and no matter what the change in DA is, IMV.

[/QUOTE Since your not running meth i would bet your IAT's are getting high and probably the way the tune is set up it's pulling timing.

It's an ecs kit. I installed everything myself and Dave Steck tuned it. I have a dashlogic but have not being able to install a wideband yet. Car has a cam that was cut for n/a and ran great while na and now with the blower too. I think something is happening while at the track because on the street the car is a beast. At the track is a different story and I dont know why. Heatsoak and high IATs are the norm at the track. Yesterday the car just blew away the tires. I'm going to have to buy me the hp software to datalog.
I'll bet it's something simple in the tune and you'll soon get it sorted and be grinning from ear to ear.
Keep us apprised of how it goes. Wish there was more I could do to help, but I don't have any real experience with ECS kits.

Something's not right there. From all that I've seen on these forums, you certainly have the right kit and the right tuner to make that thing runs low 10s at 135+ with ease before even touching meth. You definitely need to datalog it. Might also be something stupid like the throttle body closing on you or something?

I'm going out of state for about a month and half for some military school so no more testing for a while.
I was hoping that even with ****** 60ft my mph would be high but that wasnt the case. I may have to drop her off with dave when I get back. If it turns out to be high IATs or heat soaking well I may have to reconsider the meth. If it's running out of fuel well an upgrade will have to be done.

Something definitely WAY wrong.. I'd start out with a compression/leak down test.. If that checks out, then start logging...
Even spinning the tires hard, your mph should have been atleast 10 mph higher...(unless you were still spinning at like half track..LOL).
FWIW my buddy's 2012 GS with only a cam/exh/converter went 11.0@126 just a couple Friday's ago in +1000' DA... It made 495 rwhp locked.
Either yours is hurt, you are getting major KR or the throttle is closing on you some....something weird. Need to make sure youre not getting belt slip or boost leaks etc etc... Time to start some serious logging and reading plugs.
Your mph is what a bolt on LS3 runs..
Even on an off day, I would expect you to go 10.30s@132+..and that's on the slow end of where it "should" be...

What can cause the IATs to get high so quick in the middle of a run? With the temps in the low 50s and after my burnout of course my coolant temps are by that point around 210 but the IATs shoot up to over 133 by half track!!

Why not just put meth on it, stay on top of the kit's monitoring and maintenance and it will be fine... It will help with KR a bunch.
I would pressurize the blower inlet and the whole intake system up to about 15 psi with regulated air, go over everything with soapy water and look for leaks. Also make sure the BOV is sealing off well under boost.
For the 200+ HP you are missing, I'd be looking for something SIGNIFICANT honestly..
What did Dave say about it? At this point, you could pull the blower off and go faster...LOL
BTW, they ALL "feel" fast on the street... That car doesn't know if its on the street or the track so likely its running the same everywhere.
Check all the obvious stuff, if all checks out well, then get it back on the dyno and see where its at...

Call Doug with install questions/troubleshooting. Have someone else near you familiar with the kit check your install. Deal with Dsteck re: everything else. Too many cooks in the kitchen otherwise.

Lots of expert's advice too!
Strange how that works on these forums. Some poor guy posts a thread with some problem he's experiencing with his car. Then some members jump in to offer some words of encouragement or advice, then before you know it, they're being flamed or scoffed at because they were trying to help, admittedly within their own limitations.
I sometimes wonder what some members think these forums are intended for? An advertisement platform for their latest gadgets and gimmicks, perhaps?
IDK who else on this thread could be accused of purporting to be an expert, but I certainly wasn't.
Hopefully, the OP will get his car sorted soon. Maybe, just maybe, some sarcasm will help him cure it.
