Hey everyone. I haven't posted till now but have enjoyed reading all of your posts over the last couple of years or so. Lots of good info here.

Just thought I would get a few opinions on this. I have an '88 F250 with an ATS 088 turbo system on it. Love the truck. I just don't get much boost. typically 3-5 psi. If I really jam on it I can get 7-9 but the EGTs come up so fast I can only get it there and then I have to back right off. The truck is almost difficult to drive even empty because the EGTs will just heat up so quick on any kind of hill, can't even drive it to it's potential because I have to back off all the time. Pulling is even more of a chore with the EGT problem.

I figure I should back the fuel off some but the low boost just ticks me off. I think if I was able to get more boost without working it so hard to get there my problem might be alleviated.

I only let the EGTs get to about 900-1000 because the pyrometer probe is mounted in the turbo casting itself, exhaust side (looks to be the stock ATS location, kind of a stupid place. I used to mess with the Chev 6.2s a lot and the Banks kits always had the probe in the manifold--way better idea).

Anyway, any thoughts or ideas would be appreciated. Thanks.

 

I'd get the pyro switched ASAP.

High EGT's could be due to a restricted exhaust system.
If you have a cat on it, or a small exhaust pipe. I'd look there.
