what could cause overall slowness?

[mk2novagte]

my XE isnt pulling as well as it should im working out.

As with a powercap and other mods it cant even puill away from a standard mk2 gte lol.
Apart from a very tired engine, which i reckon would run awfully, What could cause the engine to be slower overall?

In the next month im getting a 2.25" full system to let it breath a bit more, and changing the AFM, Filter and intake piping.

Also hoping to get it RR'd, but at the mo im just asking people waht they think.
Im pretty sure i have a long ratio F 16 (not cr i dont think), and i thought this could knock off acceleration quite noticably? What you lot think

sorry for the essay but its annoying me

the box wouldnt cause a very noticable slowness how many miles has the engine done?

I had this problem car felt slower still ran fine, ended up being the o2 sensor that was shagged.

im thinking the engines done around 110 - 125k

The AFM is a bit gunked up so im changing that, i'll change the lambda when i put the new system on.

Idea's as its really frustrating, especially with the powercap on.

What do you mean about the powercap? It makes it worse? They dont really help performance anyway

[mk2novagte]

powercap just simplifies the intake im sure! Cant decrease performance!

If anyone knows mol, i think it was his but has had a few owners since!
