Hello everyone!
I have a 740 turbo 1986, b230ft, lh2.2. It has some small improvements in terms of power such as IPD turbo cam, ecu chip, 2.5 exhaust, 14 psi boost, K & N cone filter, etc. etc. I think it would have around 200 hp.
It really became a very fun car to drive.
But I have a problem, when I accelerate it to 100% it makes a small "cut".
I removed the "Boost Pressure Over-Pressure Switch" under the dash, and it has improved, but still has that cut when I'm accelerating it to the maximum.
Do you think it's the MAF sensor?
Do some research on the web, and I found the following: "boost increases on the pre 1990 models should be combined with the 76mm MAF found on the 1991-1994 960s The standard MAF will max out on boost increases and lead to a cutting of fuel. "
I do not have any boost leak, the injectors (stock) work properly, the spark plugs and spark plug wires also. Everything seems to be working well.
What is your opinion? can it be the MAF? If that were the problem, which MAF should I use?
My english isnt very well, Hope you guys can understand me!
Thanks for the help!!
