Ok guys, this is my first manual and turbo'd car. So these things im mentioning are a first for me and I dont know what they feel like at all.
I have a 92 laser rs turbo w/ stock motor w/ boost controller set at lowest which is 10psi.
I installed a 3inch dp, tp, and exhuast. I started to get fuel cut like crazy on a 14b and stock injectors. I do have a wally 255. I then got a afc and fixed that problem and fixed it.
After one week of learning to tune the car on the low throttle, winter came along. I took it out 2 weeks ago on some pretty decent 55 degree weather. I re-tuned my car and she was running like a champ.
Now im getting problems. When I hit fuel cut before, trust me, I know what it sounds and feels like now. Now when I floor it, and hit around 3800-4100rpms the car goes to crap. I hear a low machine gun like thud. The rpms slowly climb and when I say slow, I mean slower acceleration then daily driving at 10 percent throttle, but the car falls on its face. I also found out that if i let of full throttle and feather it, I can get my go power back but it just comes back.
I explained what I hear to my local dsm tech. He said it sounds like I may have reached my 1g as limit and should get a 2g mas. He also asked me what my wideband does when I hit this. Sometimes it flutters back and forth about .50 from where its reading but mostly I see it going to mid to low 12's. This only happens when I get on it.
He also says maybe boost leak.
Somone told me he hadnt felt this before but feels maybe its bogging on me or felt like spark.
Wenesday is my day off and im goignt to make sure my intake tube and my stock IC piping is nice and sealed.
Thanks for anyones help and I appreciate it so much. I have all I need to go really fast but refuse to move on until I fix this problem.
Thank you
Cory
