Only thing that worries me is it seems to be working fine idling and cruising. I did another pull I was melting the tires off in second and the gauge went 21.0. Doesn't feel like I'm loosening power
Like the title says did a 3dr and 4th gear pull and wideband spiked 21.0. At wot it was good at 11.3-11.8. Volts was above 14. Car still feels like it was pulling but i let out pretty quickly
Bad sensor?
Bad gauge?
Or fuel pumps?

My voltage is good now. My imrc plates are wired open. I did fuel pressure check it's good under normal driving but when I go wot the pressure starts to drop then spikes back up. I'm pretty sure the pump is just weak. It does have 202k miles on it.
Got a bore scope in it there a small puddle of oil on the piston. did a pressure test I'm pretty sure my rings are gone in cylinder 7 the cylinder wall looks alright.
I did a third gear pull last and came to a stop and a huge cloud of smoke rolled past me. The smoke is blue with a little white can smell The oil and kinda sweet. The air to fuel stayed right at 12.0 on the widband. has 2.76 upper and 4lb lower on e85 and posi ported blower. With all supporting...
I hope it's just the pump wearing out and its not sustaining enough fuel pressure. I'm running out of options on what is causing my cut out and stumble.
I'm running dual walbro 255 with kbbp on my 03. They seem to work good.
My 98 cobra cuts out and bogs at wot runs fine just normal driving. I don't know why.
I changed plugs and fuel filter and cleaned maf and cps no vacuum leeks.
I was having voltage problems fixed it with a new alternator hoping that would fix it.
I'm leaning towards fuel pump. I'll be checking...
03 I bought it with all the work done to it. I don't like to do that but only paid 13,700 for a 64k mile car.
The guy I bought it from said it made 510 to the wheels on 93. It's on e85 but it was a road tune.
Any ideas on how much it makes now on e85??
