I see your point and believe this to be some what true, but why do some of us only have it in certain gears? Any other gear in my car it will pull like a freight train as soon as you shift to 4th and stab it, knock. You would think it would be the same through the entire RPM range for all...
Your most diffidently are not alone, mine is even weirder... only does it in 4th gear, mash it knock up to 6 to 8, hard shift from 3rd same thing, but just ease into it and nothing. any other gear hard from 2nd to 3rd neg knock all the way up. figure that one out and ill give ya a cookie... lol
Dyno is always one thing, I want to see some 1/4 mile out of this thing. You have put a ton of work into it and deserve some results to brag about... looks killer with those wheels by the way!!
It is a better upgrade, just need to tune and pully properly and you will have no problems making what you want (within the limits of that blower of course)
Really hoping for you this is not going to turn into neither one have insurance, usually anyone that pushes cash that's the case or there something else going on. you need to get it reported and get it out of there asap
+100 with all of above, run far far away from this shop and have it fixed the right way. diffidently get an insurance claim and police report to back it up!!!! I would not have even moved the car without the cops involved, sounds like a scam
No my head unit is smooth as butter, I was actually going to set a glass of water on top of it, but thought better of the mess it would make if it did fall over... lol
